The GCF is 1.
Not sure about the greatest commom factor, but the greatest common factor is b.
a is 3m b is 3n m and n are relatively prime - they do not have any common factors. a2 = 9m2 Since m had no factors in common with n, m2 also has no factors in common with n. We know that 3 is a common factor of a and b. The only new possible factor between a2 and b is the second 3 when a is squared. We do not know whether b had more than one factor of 3. So, the greatest common factor of a2 and b, when the greatest common factor of a and b is 3, is either 3 or 9.
The greatest factors of A, B, and C, respectively, are the absolute values of A, B, and C. The greatest common factor of A, B, and C is 1.
The correct answer is B. The greatest common factor of 24 and 64 is 8.
The GCF is 1.
The GCF is 1.
For any two natural numbers a and b, if adivides b then greatest common factor of a and b is a.Here 3 divides 54. So, greatest common factor of 3 and 54 is 3.
The GCF is b.
6b
The GCF is 1.
The greatest common factor of a prime number(a) and a composite number(b) is 1 if b is not divisible by a.Here, 48 is not divisible by 7. Therefore, GCF(48, 7) = 1.
Since 18 is a factor of 144, it is automatically the GCF.
