The common factors are: 1, 3
3 and 1.
The only common factors are: 1, 3
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 39 are 1, 3, 13, and 39. The common factors are 1 and 3. Therefore, the greatest common factor is 3.
Since 13 is a factor of 39, all of its factors are common.
36: 1,2,3,4,6,9,12,18,36 39:1,3,13,39
The Greatest Common Factor of 36, 54: 18
The LCM of 36 and 39 is 468.
26, 36, 39, 52 and 78 are all factors of 468.
The common factors of 13 and 39 are: 1 and 13
The common factors of 39 and 91 are: 1 and 13
The common factors of 27 and 39 are 1 and 3
