Given Numbers are 70, 76

We can find the LCM of 70, 76 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 70 and 76

Multiples of 70 =70,140,210,280,350,420,490,560,630,700,770,840,910,980,1050,1120,1190,

Multiples of 76 =76,152,228,304,380,456,532,608,684,760,836,912,988,1064,1140,1216,1292,

Now, get the least common multiple of 70, 76 which is 2660

So, the LCM of 70, 76 is 2660.

One method for determining the LCM of 70 and 76 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 70's prime factorization:

Prime factors of 70 are 2, 5,7.

70 = 2¹×5¹×7¹

And this is 76's prime factorization:

Prime factors of 76 are 2,19.

76 = 2²×19¹

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, 5,7,19

2²×5¹×7¹×19¹ = 2660

This shows that the LCM of 70 and 76 is 2660.

The first step in determining the Least Common Multiple of 70 and 76 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 70 and 76:

Lets look at the first ten multiples of these numbers, 70 and 76:

70,140,210,280,350,420,490,560,630,1190 are the first ten multiples of 70.

76,152,228,304,380,456,532,608,684,1292 are the first ten multiples of 76.

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 70 and 76, for example, are 840, 1190, and 1216. 2660 is the least common multiple since it is the smallest.

70 and 76 have an LCM of 2660.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 70 and 76, than apply into the LCM equation.

GCF(70,76) = 2
LCM(70,76) = ( 70 × 76) / 2
LCM(70,76) = 5320 / 2
LCM(70,76) = 2660
