A factor of a number is any number that the original number can divide by evenly. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18 and 36. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84. The shared factors of all 3 numbers are 1, 2, 3 and 6.
Common factors of 36 and 84 are: 1, 2, 3, 4, 6, and 12.
It is 12. Beacause the factors of 36 are: 1,36,3,12,4,9,6 and the factors of 84 are: 1,84,7,12 12 is the highest factor that both numbers have in common.
The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84 The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
For 36, 2 and 3 For 90, 2, 3 and 5
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
2 and 4
The common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18
Common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18.
60, 72, 84, 90 and 96
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36.Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.GCF (36, 60, 84) = 12
a + b = 90, ie a = 90 - b;a = 2b - 36 so 2b - 36 = 90 - b ie 3b = 126 so b = 42 and a = 48 (which is 36 less than 84)
