The GCF is 15.
The GCF is 15.
That would be 15. Only a number ending in five would be a factor of 75. 45 is not. 35 is not. 25 is not. 15 is, and it also is a factor of 90. This makes it the highest common factor of 75 and 90, although it is not a prime factor.
The highest common factor is 75
The GCF of 45 75 and 135 is 15.
1 and the highest common factor is 15
The greatest common factor of 45 and 75 is 15, because it is the highest number that will divide into 45 and 75 evenly.The prime factorization of 45 is 3*3*5The prime factorization of 75 is 3*5*5The common prime factors are 3*5 = 15, so that is the GCF.The GCF is 15.It is: 15
