Hello, Math Aces! Today, we're diving into the exciting world of factors. Specifically, we’ll explore the factors of 18. Are you ready for this math adventure? Let’s go!
What Are Factors?
A factor is a number that divides another number without leaving a remainder. When we talk about the factors of 18, we're looking for all the numbers that can be multiplied together to give us 18.
How to Find Factors of a Number
To find the factors of 18, we start with the number 1 and go up to 18, checking which numbers divide 18 without any remainder.
Factor Pairs of 18
When we list the factor pairs of 18, we get:
1 and 18: 1×18=18
2 and 9: 2×9=18
3 and 6: 3×6=18
So, the factors of 18 are 1, 2, 3, 6, 9, and 18. Pretty cool, right?
Finding Common Factors
Let's say we want to find common factors between 18 and another number, like 24. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The common factors of 18 and 24 are 1, 2, 3, and 6.
Greatest Common Factor (GCF)
The greatest common factor (also called the highest common factor or HCF) is the largest number that both numbers share as a factor. For 18 and 24, the GCF is 6.
