One way is to list the factors.
Example: 30 and 42
The factors of 30 are:
1, 2, 3, 5, 6, 10, 15, 30
The factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42
The common factors are:
1, 2, 3, 6
The Greatest Common Factor:
GCF = 6
Another way is to factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF

Can you find the HCF of 3 numbers using euclids division lemma?
Yes.First find the HCF of two of the numbers, then find the HCF of that answer and the third number.In this way you could find the HCF of as many numbers as you want.

Why do you factor numbers in algebra?
to find a factor of a number you have to 1. find the hcf (highest common factor) 2. find how many times the hcf goes into your number AND THAT IS YOUR ANSWER!
