Calculate the LCM of 124,507,784,663,478

Given numbers are 124,507,784,663,478

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

The LCM of 124,507,784,663,478 is 50064806064.

Find LCM of 124,507,784,663,478 with Prime Factorization


2 124, 507, 784, 663, 478
2 62, 507, 392, 663, 239
3 31, 507, 196, 663, 239
13 31, 169, 196, 221, 239
31, 13, 196, 17, 239

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

2 x 2 x 3 x 13 x 31 x 13 x 196 x 17 x 239 = 50064806064

Therefore, the lowest common multiple of 124,507,784,663,478 is 50064806064.

LCM Formula to Find Lowest Common Multiple of 124,507,784,663,478

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.

124 x 507 x 784 x 663 x 478 = 15620219491968

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.

124 : 1, 2, 4, 31, 62, 124

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

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

663 : 1, 3, 13, 17, 39, 51, 221, 663

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,507,784,663,478, is 1.

Now, the common factors can be found like this.

124:2x 2x 31

507:3x 13x 13

784:2x 2x 2x 2x 7x 7

663:3x 13x 17

478:2x 239

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 2x 3x 13 = 312

Therefore, the value for common factors is 312.

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 = 15620219491968/(1x312)

LCM = 15620219491968/312

LCM = 50064806064

Thus, we can understand that the LCM of 124,507,784,663,478 is 50064806064.
