Given numbers are 642,780,406,114,157

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

The LCM of 642,780,406,114,157 is 50539119540.

Find LCM of 642,780,406,114,157 with Prime Factorization

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

2 x 3 x 107 x 130 x 203 x 19 x 157 = 50539119540

Therefore, the lowest common multiple of 642,780,406,114,157 is 50539119540.

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 780 x 406 x 114 x 157 = 3638816606880

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

406 : 1, 2, 7, 14, 29, 58, 203, 406

114 : 1, 2, 3, 6, 19, 38, 57, 114

157 : 1, 157

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,780,406,114,157, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

780:2x 2x 3x 5x 13

406:2x 7x 29

114:2x 3x 19

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 3 = 72

Therefore, the value for common factors is 72.

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 = 3638816606880/(1x72)

LCM = 3638816606880/72

LCM = 50539119540

Thus, we can understand that the LCM of 642,780,406,114,157 is 50539119540.
