The GCF is 1.
The GCF is 5.
The GCF of 20 and 40 is 20 The GCF of 15 and 30 is 15 The GCF of 15, 20, 30 and 40 is 5.
The answer is 1
The GCF is 2. The LCM is 240.
The GCF is 1 this is a lie
The GCF is 5.
No, it is 3:Factors of 12: 1, 2, 3, 4, 6, 12Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30Factors of 15: 1, 3, 5, 15GCF (12, 24, 30, 15) = 3
The GCF of 15, 20, and 30 is 5.5
It is 3
3
The GCF of 12, 15, 18, and 30 is 3.
12 = 1 x 22 x 3 15 = 1 x 3 x 5 20 = 1 x 22 x 5 There is no need to factor 30; at this point, the GCF is already 1 (since 12 has no 5's, 15 has no 2's, and 20 has no 3's).
