One method for determining the LCM of 7020 and 7028 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 7020's prime factorization:

Prime factors of 7020 are 2, 3, 5,13.

7020 = 2²×3³×5¹×13¹

And this is 7028's prime factorization:

Prime factors of 7028 are 2, 7,251.

7028 = 2²×7¹×251¹

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, 3, 5,13, 7,251

2²×3³×5¹×7¹×13¹×251¹ = 12334140

This shows that the LCM of 7020 and 7028 is 12334140.

The first step in determining the Least Common Multiple of 7020 and 7028 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 7020 and 7028:

Lets look at the first ten multiples of these numbers, 7020 and 7028:

7020,14040,21060,28080,35100,42120,49140,56160,63180,119340 are the first ten multiples of 7020.

7028,14056,21084,28112,35140,42168,49196,56224,63252,119476 are the first ten multiples of 7028.

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 7020 and 7028, for example, are 84240, 119340, and 112448. 12334140 is the least common multiple since it is the smallest.

7020 and 7028 have an LCM of 12334140.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 7020 and 7028, than apply into the LCM equation.

GCF(7020,7028) = 4
LCM(7020,7028) = ( 7020 × 7028) / 4
LCM(7020,7028) = 49336560 / 4
LCM(7020,7028) = 12334140
