The factors of 12 are:
1, 2, 3, 4, 6, 12
The factors of 18 are:
1, 2, 3, 6, 9, 18
The factors of 24 are:
1, 2, 3, 4, 6, 8, 12, 24
The common factors are:
1, 2, 3, 6
The Greatest Common Factor:
GCF = 6
Write the numbers are products of their prime factors:
12 = 2*2*3
18 = 2*3*3
24 = 2*2*3*3
The factors that are common to all three numbers are 2 and 3 so the GCF = 2*3 = 6
LCM(12, 18, 24) = 72; GCF(12, 18, 24) = 6.
The GCF of 24 and 12 is 12.
The GCF is 6.
The GCF is 6.
You need at least two numbers to find a GCF. The GCF of 18 and 24 is 6.
Greatest common factor of 12 and 18 and 24 is 6.
The GCF of 12, 18, 24, and 30 is 6.
The GCF is 6.
The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
