What is GCF in math example?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.
For example, 12, 20, and 24 have two common factors: 2 and 4.
The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
GCF is often used to find common denominators.
How do you find the GCF and LCM fast?
How to Find the LCM – FAST!!!
- Step 1) Find the GCF for the two numbers. For 18 and 30, GCF is 6.
- Step 2) Divide that GCF into either number; it doesn’t matter which one you choose, so choose the one that’s easier to divide. Choose 18.
- Step 3) Take that answer and multiply it by the other number.
- Step 4) Celebrate …
