Given numbers are 455,239,856,478

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

The LCM of 455,239,856,478 is 93085720.

Find LCM of 455,239,856,478 with Prime Factorization

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

2 x 239 x 455 x 1 x 428 x 1 = 93085720

Therefore, the lowest common multiple of 455,239,856,478 is 93085720.

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.

455 x 239 x 856 x 478 = 44494974160

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

239 : 1, 239

856 : 1, 2, 4, 8, 107, 214, 428, 856

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,239,856,478, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

239:239

856:2x 2x 2x 107

478:2x 239

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

2x 239 = 478

Therefore, the value for common factors is 478.

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 = 44494974160/(1x478)

LCM = 44494974160/478

LCM = 93085720

Thus, we can understand that the LCM of 455,239,856,478 is 93085720.
