Given numbers are 121,784,478,204,436

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

The LCM of 121,784,478,204,436 is 126036405264.

Find LCM of 121,784,478,204,436 with Prime Factorization

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

2 x 2 x 121 x 196 x 239 x 51 x 109 = 126036405264

Therefore, the lowest common multiple of 121,784,478,204,436 is 126036405264.

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.

121 x 784 x 478 x 204 x 436 = 4033164968448

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.

121 : 1, 11, 121

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

478 : 1, 2, 239, 478

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,784,478,204,436, is 1.

Now, the common factors can be found like this.

121:11x 11

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

478:2x 239

204:2x 2x 3x 17

436:2x 2x 109

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 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 4033164968448/(1x32)

LCM = 4033164968448/32

LCM = 126036405264

Thus, we can understand that the LCM of 121,784,478,204,436 is 126036405264.
