Calculate the LCM of 215,170,374,691

Given numbers are 215,170,374,691

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 215,170,374,691 is 55563310.

Find LCM of 215,170,374,691 with Prime Factorization


2 215, 170, 374, 691
5 215, 85, 187, 691
17 43, 17, 187, 691
43, 1, 11, 691

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 17 x 43 x 1 x 11 x 691 = 55563310

Therefore, the lowest common multiple of 215,170,374,691 is 55563310.

LCM Formula to Find Lowest Common Multiple of 215,170,374,691

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

215 x 170 x 374 x 691 = 9445762700

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

215 : 1, 5, 43, 215

170 : 1, 2, 5, 10, 17, 34, 85, 170

374 : 1, 2, 11, 17, 22, 34, 187, 374

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,170,374,691, is 1.

Now, the common factors can be found like this.

215:5x 43

170:2x 5x 17

374:2x 11x 17

691:691

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 17 = 170

Therefore, the value for common factors is 170.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 9445762700/(1x170)

LCM = 9445762700/170

LCM = 55563310

Thus, we can understand that the LCM of 215,170,374,691 is 55563310.
