Factors of a number are smaller (and equal) numbers that divide into the original number to give a whole number as the answer. Eg - 12 is a factor of 36 because 36/12 = 3 (a whole number.)
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Factors of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
So the common factors are the ones in each list:
1, 2, 3, 4, 6, 12
1,2,3,4,6,12
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 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96. The factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108. The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12.
The greatest common factor of 72 and 96 is 24.
60, 72, 84, 90 and 96 each have twelve factors.
The greatest common factor of 36, 60, and 96 is 12
The common factors are: 1, 2, 3, 4, 6, 8, 12, 24
The first step to find the gcf of 96 and 72 is to list the factors of each number. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48 and 96. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.
1,2,3,4,6,8,12,24
1,2,3,4,6,12
1,2,3,4,6,12
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
36= 2x2x3x3 96= 2x2x2x2x2x3 2x2x2x3= 24, 48, 72
1, 2 and 4
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
The common factors are: 1, 2, 3, 4, 6, 8, 12, 24.
The greatest common factor is 12.12 * 8 = 9612 * 3 = 3612 * 6 = 72
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The prime factors of 72 are: 2 and 3.The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.The prime factors of 96 are: 2 and 3.
