Calculate the LCM of 291,392,131,836

Given numbers are 291,392,131,836

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

The LCM of 291,392,131,836 is 3123177288.

Find LCM of 291,392,131,836 with Prime Factorization


2 291, 392, 131, 836
2 291, 196, 131, 418
291, 98, 131, 209

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

2 x 2 x 291 x 98 x 131 x 209 = 3123177288

Therefore, the lowest common multiple of 291,392,131,836 is 3123177288.

LCM Formula to Find Lowest Common Multiple of 291,392,131,836

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.

291 x 392 x 131 x 836 = 12492709152

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.

291 : 1, 3, 97, 291

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

131 : 1, 131

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,392,131,836, is 1.

Now, the common factors can be found like this.

291:3x 97

392:2x 2x 2x 7x 7

131:131

836:2x 2x 11x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 12492709152/(1x4)

LCM = 12492709152/4

LCM = 3123177288

Thus, we can understand that the LCM of 291,392,131,836 is 3123177288.
