## What is a GCF and LCM?

The greatest common factor (GCF) is the largest number that is a factor of two or more numbers, and the least common multiple (LCM) is the smallest number that is a multiple of two or more numbers. …

How do you use GCF in real life?

We use greatest common factors all the time with fractions, and as fractions are used a lot in everyday life, this makes GCF very useful! By finding the GCF of the denominator and numerator, you can then successfully simplify a fraction or ratio. E.g. We can simplify 3045 by knowing that its HCF is 15 .

What is the difference between a GCF and a whole number?

There isn’t much of a difference. GCF, which stands for “Greatest common factor”, is the largest value of the values you have, that multiplied by whole number is able to “step onto both”. For example, the GCF of 27 and 30 is 3, since if you add 3 repeatedly, it will equal 27 after it is added 9 times and equal 30 after adding 3 10 times.
