1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 8001, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800.
The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200. The prime factors are of 200 are 2 x 2 x 2 x 5 x 5.
The least common denominator will be the least common multiple between 8 and 10, which is 40. So convert the fractions to a denominator of 40.40 = 8 x 5, so for 5/8, multiply top and bottom by 5 -> 25/4040 = 10 x 4, so for 7/10, multiply both by 4 -> 28/40.So now you have 5/8 = 25/40 and 7/10 = 28/40. You can add them and get 53/40, or 1 13/40. You can compare them and find that 25 < 28, so 5/8 < 7/10.
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 32 are 1, 2, 4, 8, 16, and 32. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8.
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 8: 16, 24, 32, 40 10: 10, 20, 30, 40 The least common multiple for 8 and 10 is 40.
Common factors of 20, 25, and 40 are: 1 and 5.
The common factors of 20, 25, and 40 are 1 and 5.
Factors of 20: 1, 2, 4, 5, 10, 20 Factors of 25: 1, 5, 25 Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40 GCF (20, 25, 40) = 5
