What is LCM of 73 and 77

Given Numbers are 73, 77

We can find the LCM of 73, 77 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 73 and 77

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

Multiples of 77 =77,154,231,308,385,462,539,616,693,770,847,924,1001,1078,1155,1232,1309,

Now, get the least common multiple of 73, 77 which is 5621

So, the LCM of 73, 77 is 5621.

Least Common Multiple (LCM) of 73 and 77 with the help of Prime Factorisation

One method for determining the LCM of 73 and 77 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 73's prime factorization:


73 73
1

Prime factors of 73 are 73.

73 = 731

And this is 77's prime factorization:


7 77
11 11
1

Prime factors of 77 are 7,11.

77 = 71×111

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:73, 7,11

.

71×111×731 = 5621

This shows that the LCM of 73 and 77 is 5621.

How to Calculate the LCM of 73 and 77 Using Common Multiples

The first step in determining the Least Common Multiple of 73 and 77 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 73 and 77:

Lets look at the first ten multiples of these numbers, 73 and 77:

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

77,154,231,308,385,462,539,616,693,1309 are the first ten multiples of 77.

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 73 and 77, for example, are 876, 1241, and 1232. 5621 is the least common multiple since it is the smallest.

73 and 77 have an LCM of 5621.

Least Common Multiple of 73 and 77 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 73 and 77, than apply into the LCM equation.

GCF(73,77) = 1
LCM(73,77) = ( 73 × 77) / 1
LCM(73,77) = 5621 / 1
LCM(73,77) = 5621
