Whole Numbers in Math is really a tough topic but luckily, we will help you to understand what whole numbers are. In maths, Whole Numbers are simply any number that is not a fraction. Furthermore, whole numbers also include positive and negative integers. We can find factors of the Whole number by dividing it with any two different numbers and then find which factors are shared by both of them.
What are Whole Numbers in Math?
Whole numbers are the basic numbers we use in everyday life. They are the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. We can use them to count things or to measure how far apart they are.
We can also use whole numbers to make calculations like addition and subtraction. In maths, we sometimes call these operations “functions.” So whole numbers are a very important part of mathematics!
How to find the factors of a whole number?
To find the factors of a whole number, you need to know what a factor is. A factor is a number that divides evenly into another number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. To find the factors of a whole number, you can use a factor tree.
A factor tree is a way to find the factors of a number by breaking it down into smaller numbers. To use a factor tree, you start with the number you want to find the factors of. Then, you break that number down into two smaller numbers. You continue to break down those numbers until you get to numbers that are only divisible by 1 and themselves. Those are the factors of your original number!
Let’s use a factor tree to find the factors of 48. We’ll start with 48:
48 ÷ 2 = 24
24 ÷ 2 = 12
12 ÷ 3 = 4
From there, we can see that the factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
The Greatest Common Factor
The greatest common factor of two or more whole numbers is the largest positive integer that divides evenly into each of the numbers. For example, the greatest common factor of 24 and 36 is 12. To find the greatest common factor of two numbers, start by finding all of the factors of each number. Then, identify the largest number that appears in both lists of factors. This number is the greatest common factor.
Divisibility Rules
There are several rules of divisibility that can be used to determine whether or not a given number is a whole number. These rules include:
- A number is divisible by 2 if it is even.
- A number is divisible by 3 if the sum of its digits is divisible by 3.
- A number is divisible by 4 if the last two digits are divisible by 4.
- A number is divisible by 5 if it ends in a 0 or 5.
- A number is divisible by 6 if it is divisible by both 2 and 3.
- A number is divisible by 8 if the last three digits are divisible by 8.
- A number is divisible by 9 if the sum of its digits is divisible by 9.
- A number is divisible by 10 if it ends in a 0.
Using these rules, we can determine whether or not a given number is a whole number. For example, let’s say we’re given the number 24. We can immediately see that 24 is even, so we know it’s divisible by 2. We can also see that the sum of its digits (2 + 4) ia 6, which is also indicate at least it’s dıvısible by 3 and probably companies dıvısible (24/3=8)
With this you can also improve your grammar from IELTS by taking classes and tips from experts.
Conclusion
Whole numbers in maths are pretty simple to understand – they’re just the numbers we use for counting. But once you start using them in equations and other maths problems, they can be a little more tricky. This article should have given you a good understanding of what whole numbers are and how to use them in your maths equations. If you still have questions, be sure to ask your teacher or another maths expert.
