The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 The factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40The factors of 55 are 1, 5, 11, 55 The factors of 75 are 1, 3, 5, 15, 25, 75
trick question, the number zero is in the list, therefore there is no common factors between all of these numbers
The factors of 55 are 1, 5, 11, 55.
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 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The factors of 55 are 1, 5, 11, and 55. The common factors are 1 and 5. Therefore, the greatest common factor is 5.
Well, isn't that a happy little math problem! To find 55 percent of 40, you simply multiply 40 by 0.55 (which is the decimal form of 55 percent). So, 40 multiplied by 0.55 equals 22. You've just painted a beautiful mathematical equation!
-55
(56/55) / (77/40) = (56/55) * (40/77) =56*40/(55*77) = 8*40/(55*11) = 8*8/(11*11) = 64/121
220 has 12 factors: 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
55 has four factors... 1, 5, 11 & 55
1.375
55 multiplied by 40 equals 2,200.
40 + 15 = 55
