Least Common Multiple (LCM) of 7040 and 7046 with the help of Prime Factorisation

One method for determining the LCM of 7040 and 7046 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 7040's prime factorization:


2 7040
2 3520
2 1760
2 880
2 440
2 220
2 110
5 55
11 11
1

Prime factors of 7040 are 2, 5,11.

7040 = 27×51×111

And this is 7046's prime factorization:


2 7046
13 3523
271 271
1

Prime factors of 7046 are 2, 13,271.

7046 = 21×131×2711

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, 5,11, 13,271

.

27×51×111×131×2711 = 24801920

This shows that the LCM of 7040 and 7046 is 24801920.

How to Calculate the LCM of 7040 and 7046 Using Common Multiples
