The factors of 66 are:
1, 2, 3, 6, 11, 22, 33, 66
The factors of 90 are:
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
66% of 90= 66% * 90= 0.66 * 90= 59.4
66, 90, & 115 Reduce each number to its prime factors. Hence 66 = 11,3,2 90 = 18,6 = 3,6,6 = 3,3,3,2,2 115 = 5,23 The HCF between 66, & 90 is 3,2 = 6 There is no common factor between 115 and 66,90.
GCD(66, 90) = 6
The factors of 42 are 1,2,3,6,7,14,21,42. The factors of 66 are 1,2,3,6,11,22,33,66
ANSWER: 73.33%% rate:= 66/90 * 100%= 0.7333 * 100%= 73.33%
The prime factors of 66 are: 2 3 11
The product of the prime factors is 66. See:2 * 3 * 11 = 66
180 minus 66 minus 90 = 24.
66/540 = 11/90
Factors of 90 will be factors of 180.
The factors of 66 are 1, 2, 3, 6, 11, 22, 33, 66. For them to be common, they need to be compared to another set of factors.
The factors of 21 are: 1, 3, 7, 21 The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66
