Calculate the LCM of 838,956,507,394,117

Given numbers are 838,956,507,394,117

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

The LCM of 838,956,507,394,117 is 120023795268.

Find LCM of 838,956,507,394,117 with Prime Factorization


2 838, 956, 507, 394, 117
3 419, 478, 507, 197, 117
13 419, 478, 169, 197, 39
419, 478, 13, 197, 3

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

2 x 3 x 13 x 419 x 478 x 13 x 197 x 3 = 120023795268

Therefore, the lowest common multiple of 838,956,507,394,117 is 120023795268.

LCM Formula to Find Lowest Common Multiple of 838,956,507,394,117

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.

838 x 956 x 507 x 394 x 117 = 18723712061808

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.

838 : 1, 2, 419, 838

956 : 1, 2, 4, 239, 478, 956

507 : 1, 3, 13, 39, 169, 507

394 : 1, 2, 197, 394

117 : 1, 3, 9, 13, 39, 117

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,956,507,394,117, is 1.

Now, the common factors can be found like this.

838:2x 419

956:2x 2x 239

507:3x 13x 13

394:2x 197

117:3x 3x 13

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

2x 2x 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 18723712061808/(1x156)

LCM = 18723712061808/156

LCM = 120023795268

Thus, we can understand that the LCM of 838,956,507,394,117 is 120023795268.
