Top Answer

GCF stands for Greatest Common Factor. This means that the GCF of 45 and 75 will be the greatest common factor of 45 and 75.

The prime factorization of 45 is 3^2*5. Thus, a number is a factor of 45 if and only if it does not have more than 2 3s in its prime factorization, more than one 5 in its prime factorization, or any other prime factor.

The prime factorization of 75 is 3*5^2. Thus, a number is a factor of 75 if and only if it does not have more than one 3 in its prime factorization, more than 2 5s in its prime factorization, or any other prime factor.

Combining those two conclusions together, we get that if a number is a common factor of 45 and 75 if and only if it does not have more than one 3 in its prime factorization, more than one 5 in its prime factorization, or any other prime factor.

Since multiplying by a 3 or a 5 will only increase the value of a number, there is no reason to not include them. Thus, the GCF of 45 and 75 is 3*5 or 15.

0The GCF is 15.

No idea what the gfc is but GCF(35, 45) = 5.

The greatest common factor of both numbers is 15

5

The GCF is 3.

The GCF is 45.

The GCF is 15.

Their gcf is 15 .

The GCF is 5.

The GCF is 3.

p = 75+75+45+45=240cm a = 75 x 45 = 3375cm

33.08 is 75% of 45

.6 * 75 = 45 60 percent of 75 is 45.

It is: (75-45)/75 times 100 = 40% decrease

45 is 75% of 60

45 percent of 75 is 33.75

45

The GCF of 45 and 75 is 15

45 as a percentage of 60 is 45/60 times 100 = 75%

The GCF for 20 45 75 is 5.

1. (28 = 2 x 2 x 7, 45 = 3 x 3 x 5)

225 and 15, respectively.

gcf of 45 and 75 is 15.

45% is obviously larger than 75%... No, just joking. 75% is larger than 45%.

The GCF is the greatest common factor. The GCF of 75 and 100 is 25. This means that this is the largest number that will fit into both numbers, equally.
