Given numbers are 478,121,379,842

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

The LCM of 478,121,379,842 is 9228573442.

Find LCM of 478,121,379,842 with Prime Factorization

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

2 x 239 x 121 x 379 x 421 = 9228573442

Therefore, the lowest common multiple of 478,121,379,842 is 9228573442.

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 121 x 379 x 842 = 18457146884

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

121 : 1, 11, 121

379 : 1, 379

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,121,379,842, is 1.

Now, the common factors can be found like this.

478:2x 239

121:11x 11

379:379

842:2x 421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 18457146884/(1x2)

LCM = 18457146884/2

LCM = 9228573442

Thus, we can understand that the LCM of 478,121,379,842 is 9228573442.
