Given numbers are 638,980,319,136,374

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

The LCM of 638,980,319,136,374 is 10629080.

Find LCM of 638,980,319,136,374 with Prime Factorization

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

2 x 2 x 11 x 17 x 29 x 1 x 245 x 1 x 2 x 1 = 10629080

Therefore, the lowest common multiple of 638,980,319,136,374 is 10629080.

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.

638 x 980 x 319 x 136 x 374 = 10144904147840

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

319 : 1, 11, 29, 319

136 : 1, 2, 4, 8, 17, 34, 68, 136

374 : 1, 2, 11, 17, 22, 34, 187, 374

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,980,319,136,374, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

980:2x 2x 5x 7x 7

319:11x 29

136:2x 2x 2x 17

374:2x 11x 17

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 11x 11x 17x 29 = 954448

Therefore, the value for common factors is 954448.

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 = 10144904147840/(1x954448)

LCM = 10144904147840/954448

LCM = 10629080

Thus, we can understand that the LCM of 638,980,319,136,374 is 10629080.
