Given Numbers are 68, 73

We can find the LCM of 68, 73 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 68 and 73

Multiples of 68 =68,136,204,272,340,408,476,544,612,680,748,816,884,952,1020,1088,1156,

Multiples of 73 =73,146,219,292,365,438,511,584,657,730,803,876,949,1022,1095,1168,1241,

Now, get the least common multiple of 68, 73 which is 4964

So, the LCM of 68, 73 is 4964.

One method for determining the LCM of 68 and 73 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 68's prime factorization:

Prime factors of 68 are 2,17.

68 = 2²×17¹

And this is 73's prime factorization:

Prime factors of 73 are 73.

73 = 73¹

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: 2,17,73

2²×17¹×73¹ = 4964

This shows that the LCM of 68 and 73 is 4964.

The first step in determining the Least Common Multiple of 68 and 73 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 68 and 73:

Lets look at the first ten multiples of these numbers, 68 and 73:

68,136,204,272,340,408,476,544,612,1156 are the first ten multiples of 68.

73,146,219,292,365,438,511,584,657,1241 are the first ten multiples of 73.

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 68 and 73, for example, are 816, 1156, and 1168. 4964 is the least common multiple since it is the smallest.

68 and 73 have an LCM of 4964.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 68 and 73, than apply into the LCM equation.

GCF(68,73) = 1
LCM(68,73) = ( 68 × 73) / 1
LCM(68,73) = 4964 / 1
LCM(68,73) = 4964
