Given numbers are 476,520,387,331

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

The LCM of 476,520,387,331 is 7926642360.

Find LCM of 476,520,387,331 with Prime Factorization

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

2 x 2 x 119 x 130 x 387 x 331 = 7926642360

Therefore, the lowest common multiple of 476,520,387,331 is 7926642360.

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.

476 x 520 x 387 x 331 = 31706569440

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.

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

387 : 1, 3, 9, 43, 129, 387

331 : 1, 331

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,520,387,331, is 1.

Now, the common factors can be found like this.

476:2x 2x 7x 17

520:2x 2x 2x 5x 13

387:3x 3x 43

331:331

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 31706569440/(1x4)

LCM = 31706569440/4

LCM = 7926642360

Thus, we can understand that the LCM of 476,520,387,331 is 7926642360.
