One method for determining the LCM of 7009 and 7015 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 7009's prime factorization:

Prime factors of 7009 are 43,163.

7009 = 43¹×163¹

And this is 7015's prime factorization:

Prime factors of 7015 are 5, 23,61.

7015 = 5¹×23¹×61¹

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: 43,163, 5, 23,61

5¹×23¹×43¹×61¹×163¹ = 49168135

This shows that the LCM of 7009 and 7015 is 49168135.

The first step in determining the Least Common Multiple of 7009 and 7015 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 7009 and 7015:

Lets look at the first ten multiples of these numbers, 7009 and 7015:

7009,14018,21027,28036,35045,42054,49063,56072,63081,119153 are the first ten multiples of 7009.

7015,14030,21045,28060,35075,42090,49105,56120,63135,119255 are the first ten multiples of 7015.

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 7009 and 7015, for example, are 84108, 119153, and 112240. 49168135 is the least common multiple since it is the smallest.

7009 and 7015 have an LCM of 49168135.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 7009 and 7015, than apply into the LCM equation.

GCF(7009,7015) = 1
LCM(7009,7015) = ( 7009 × 7015) / 1
LCM(7009,7015) = 49168135 / 1
LCM(7009,7015) = 49168135
