What is the least common multiple of 3 and 7 and 5?

Answer 1

The least common multiple of 3, 5, and 7 is 105.

This is the first number that each of these numbers have in common when finding the multiples of each number. You begin by taking each number and multiplying the number by 1, 2, 3, 4, 5, etc. until you come up with a number that is common to each of the numbers (3,5 and 7). In this case, the first number that the three numbers had in common happened to be 105. The number 3 had to be multiplied 35 times (35x3=105); The number 5 had to be multiplied 21 times (21x5=105); and the number 7 had to be multiplied 15 times to have a number in common with the other two numbers (15x7=105).

Answer 2

It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!

Answer 3
