Given numbers are 478,617,688,938

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

The LCM of 478,617,688,938 is 47582181136.

Find LCM of 478,617,688,938 with Prime Factorization

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

2 x 239 x 617 x 344 x 469 = 47582181136

Therefore, the lowest common multiple of 478,617,688,938 is 47582181136.

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 617 x 688 x 938 = 190328724544

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

617 : 1, 617

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,617,688,938, is 1.

Now, the common factors can be found like this.

478:2x 239

617:617

688:2x 2x 2x 2x 43

938:2x 7x 67

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 = 190328724544/(1x4)

LCM = 190328724544/4

LCM = 47582181136

Thus, we can understand that the LCM of 478,617,688,938 is 47582181136.
