What is the common factor of 60 and 90?

The common factor of 60 and 90 can be found by finding all divisible numbers. GCF is the common number that can divide more than a number without having remainders. The first level to find the greatest common factor is to find all possible numbers that can go through the numbers.

The divisible number for 60 are 1,2,3,4,5,6,10,12,15,20,30, and 60.The divisible numbers for 90 are 1,2,3,5,6,9,10,15,18,30,45,90. Next step you have to analyze the common numbers and choose the greatest number or highest common divisor.

In this case 30 is the common and highest factor. In order words 60 and 90 common factor is 30.

30 is the correct answer to this question. The greatest common factor is commonly referred to as GCF or as a divisor. It is the largest integer that is common between the numbers and is positive. It is the last one that is without a remainder. To identify the greatest common factor, the first step is to list all of the possible numbers between both numbers.

Starting with the number 60, the possible numbers are 1, 1,2,3, 4, 5, 6, 10, 12, 15, 20, 30 and 60. With the number 90, the possible numbers are 1,2,3, 5,6,9,10,15,18,30,45 and 90. Listing those numbers out, you see that the greatest number they have in common is the number 30, which is the answer.

The greatest common factor or divisor for 60 and 90 is 30. GCF is the largest common positive integer that divides all the numbers without a remainder. The first step to locating the greatest common factor of 60 and 90 is to list all possible numbers.

The elements of 60 are 1,2,3, 4, 5, 6, 10, 12, 15, 20, 30 and 60. The elements of 90 are 1,2,3, 5,6,9,10,15,18,30,45 and 90. After that you have to analyze which are the common divisors. The greatest common factor can also be known as the greatest common measure or highest common divisor.
