Given numbers are 478,220,584,813

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

The LCM of 478,220,584,813 is 6241140840.

Find LCM of 478,220,584,813 with Prime Factorization

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

2 x 2 x 239 x 55 x 146 x 813 = 6241140840

Therefore, the lowest common multiple of 478,220,584,813 is 6241140840.

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.

478 x 220 x 584 x 813 = 49929126720

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.

478 : 1, 2, 239, 478

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

584 : 1, 2, 4, 8, 73, 146, 292, 584

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,220,584,813, is 1.

Now, the common factors can be found like this.

478:2x 239

220:2x 2x 5x 11

584:2x 2x 2x 73

813:3x 271

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 2 = 8

Therefore, the value for common factors is 8.

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 = 49929126720/(1x8)

LCM = 49929126720/8

LCM = 6241140840

Thus, we can understand that the LCM of 478,220,584,813 is 6241140840.
