What is the greatest common factor for 60 and 45

The greatest common factor (GCF) is also known as greatest common divisor (GCD).

First we have to find the prime factorization of 60

60 = 2² × 3 × 5

Then we have to find the prime factorization of 45

45 = 3² × 5

Now we have to multiply the common factors to both numbers with a lower exponent

GCF = 3 × 5 = 15

Answer : GCF(60,45) = 15

Hope this helps!

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
