Multiples of 141 =141,282,423,564,705,846,987,1128,1269,1410,1551,1692,1833,1974,2115,2256,2397,

Multiples of 147 =147,294,441,588,735,882,1029,1176,1323,1470,1617,1764,1911,2058,2205,2352,2499,

Now, get the least common multiple of 141, 147 which is 6909

So, the LCM of 141, 147 is 6909.

One method for determining the LCM of 141 and 147 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 141's prime factorization:

Prime factors of 141 are 3,47.

141 = 3¹×47¹

And this is 147's prime factorization:

Prime factors of 147 are 3,7.

147 = 3¹×7²

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: 3,47,7

3¹×7²×47¹ = 6909

This shows that the LCM of 141 and 147 is 6909.

The first step in determining the Least Common Multiple of 141 and 147 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 141 and 147:

Lets look at the first ten multiples of these numbers, 141 and 147:

141,282,423,564,705,846,987,1128,1269,2397 are the first ten multiples of 141.

147,294,441,588,735,882,1029,1176,1323,2499 are the first ten multiples of 147.

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 141 and 147, for example, are 1692, 2397, and 2352. 6909 is the least common multiple since it is the smallest.

141 and 147 have an LCM of 6909.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 141 and 147, than apply into the LCM equation.

GCF(141,147) = 3
LCM(141,147) = ( 141 × 147) / 3
LCM(141,147) = 20727 / 3
LCM(141,147) = 6909
