To solve common multiples, take the prime factorization of each number. As an example, lets look at 14, 50, and 70...

14 = 21 x 71

50 = 21 x 52

70 = 21 x 51 x 71

To find the least common multiple, take each factor present, with the maximum encountered value of its exponent, and multiply them together...

21 x 52 x 71 = 350. The LCM of 14, 50, and 70 is 350.

Not asked, but answered for completeness, to find the greatest common divisor, take each factor present, with the smallest encountered value of its exponent, and multiply them togother. Note that a missing factor effectively has an exponent of zero...

21 x 50 x 70 = 2. The GCD of 14, 50, and 70 is 2.

This cannot be answered because the common multiples of any two or more numbers are infinite.

The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.

There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.

Each common multiple of 9 and 10 occurs exactly once (in the list of common multiples), so there is no common multiple that occurs the most. All common multiples of 9 and 10 are the multiples of their least common multiple which is 90.

The common multiples of 18 and 24 are 72 and 144.

That seems like a fairly easy choice...

The answer will depend on the problem!

yes because it helps me figure out all the prime numbers!;)

They are all multiples.

Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".

you list all the multiples of each number until you come to the first number that is in all columns
