One method for determining the LCM of 974 and 978 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:

Here is 974's prime factorization:

Prime factors of 974 are 2,487.

974 = 2¹×487¹

And this is 978's prime factorization:

Prime factors of 978 are 2, 3,163.

978 = 2¹×3¹×163¹

When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 2,487, 3,163

2¹×3¹×163¹×487¹ = 476286

This shows that the LCM of 974 and 978 is 476286.

The first step in determining the Least Common Multiple of 974 and 978 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 974 and 978:

Lets look at the first ten multiples of these numbers, 974 and 978:

974,1948,2922,3896,4870,5844,6818,7792,8766,16558 are the first ten multiples of 974.

978,1956,2934,3912,4890,5868,6846,7824,8802,16626 are the first ten multiples of 978.

You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 974 and 978, for example, are 11688, 16558, and 15648. 476286 is the least common multiple since it is the smallest.

974 and 978 have an LCM of 476286.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 974 and 978, than apply into the LCM equation.
