What is the greatest common multiple of 15 and 45 and the least common multiple of 15 and 45?
The Greatest Common Factor of 15, 45: 15The Least Common Multiple of 15, 45: 45
Which common multiple of 4 and 5 is also a multiple of 15?
The least common multiple of 4 and 5 is 20. The least common multiple of 15 and 20 is 60. (Thus, the least common multiple of 4, 5, and 15 is 60.) Any multiple of 60 will also be a multiple of 4, 5, and 15.
What is the least common multiple of 14 and 70?
Since 70 is a multiple of 14, it is the least common multiple. Or, you can determine it as you would any pair of numbers. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 14 and 70 is 14. Therefore, the least common multiple 14 x 70 ÷ 14 = 70.
Least Common Multiple of 14 and 30?
The least common multiple of the numbers 14 and 30 is 210.
