You need at least two numbers to find a GCF.
At least two numbers are required for common factors
12
The highest common factor 15
60
The GCF is 15.
15 and 30 are factors of 60. The factors of 60 include the factors of 15 and 30. 45 is not a factor of 60.
The common factors of 12 and 60 are 1, 2, 3, 4, 6, 12.The highest common factor is 12.
First you find the factors of 45 and 60. The Factors of 45 are:1,3,5,9,15,and 45 The Factors of 60 are:1,2,3,4,5,6,10,12,15,20,30,60 The GCF is the highest common number so the GCF is 15.
There cannot be a common factor of just one number. You need two or more numbers.
2, 5, 10Restate the question: What are the common factors of 50 and 60?50 = 2x5x560 = 2x2x3x5The common factors are 2, 5, and 10. 10 is the greatest common factor or GCF (also called the highest common factor, HCF).
The factors of 36 are :1,2,3,6,9,12,18,36The factors of 60 are :1,2,3,5,6,10,12,15,20,30,60The factors of 108 are :1,2,3,4,6,9,12,.etc.each number has the many similar factors, but the highest factor (or GCF [greatest common factor]) is 12 Therefore the answer is 12.
Any of the factors up to 60 can be common.
The divisors of 60 are also called the factors of 60. Here they are in order: 1,2,3,4,5,6,10,12,,15,20,30,60 Least common factor: 1 Highest factor: 60 Those are all the possible whole factors of 60, including the proper factor.
