Given numbers are 642,480,121,572,157

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

The LCM of 642,480,121,572,157 is 12683916960.

Find LCM of 642,480,121,572,157 with Prime Factorization

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

2 x 2 x 3 x 11 x 107 x 40 x 11 x 13 x 157 = 12683916960

Therefore, the lowest common multiple of 642,480,121,572,157 is 12683916960.

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.

642 x 480 x 121 x 572 x 157 = 3348554077440

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

121 : 1, 11, 121

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

157 : 1, 157

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,480,121,572,157, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

480:2x 2x 2x 2x 2x 3x 5

121:11x 11

572:2x 2x 11x 13

157:157

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 11 = 264

Therefore, the value for common factors is 264.

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 = 3348554077440/(1x264)

LCM = 3348554077440/264

LCM = 12683916960

Thus, we can understand that the LCM of 642,480,121,572,157 is 12683916960.
