Given Numbers are 124, 130

We can find the LCM of 124, 130 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 124 and 130

Multiples of 124 =124,248,372,496,620,744,868,992,1116,1240,1364,1488,1612,1736,1860,1984,2108,

Multiples of 130 =130,260,390,520,650,780,910,1040,1170,1300,1430,1560,1690,1820,1950,2080,2210,

Now, get the least common multiple of 124, 130 which is 8060

So, the LCM of 124, 130 is 8060.

One method for determining the LCM of 124 and 130 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 124's prime factorization:

Prime factors of 124 are 2,31.

124 = 2²×31¹

And this is 130's prime factorization:

Prime factors of 130 are 2, 5,13.

130 = 2¹×5¹×13¹

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: 2,31, 5,13

2²×5¹×13¹×31¹ = 8060

This shows that the LCM of 124 and 130 is 8060.

The first step in determining the Least Common Multiple of 124 and 130 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 124 and 130:

Lets look at the first ten multiples of these numbers, 124 and 130:

124,248,372,496,620,744,868,992,1116,2108 are the first ten multiples of 124.

130,260,390,520,650,780,910,1040,1170,2210 are the first ten multiples of 130.

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 124 and 130, for example, are 1488, 2108, and 2080. 8060 is the least common multiple since it is the smallest.

124 and 130 have an LCM of 8060.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 124 and 130, than apply into the LCM equation.

GCF(124,130) = 2
LCM(124,130) = ( 124 × 130) / 2
LCM(124,130) = 16120 / 2
LCM(124,130) = 8060
