Question

What is the GCF of 24 30 and 42

Answer 1

Explanation:

To find the Greatest Common Factor of these numbers, write down their factors

24=2 times 2 times 2 times 3

30=2 times 3 times 5

42=2 times 3 times 7

find the numbers common to all of them and group likewise

24=(2 times 3) times 2 times 2

30=(2 times 3) times 5

42=(2 times 3) times 7

the common one among all of them is 2 times 3=6

the GCF=6
