Given numbers are 190,664,790,456,381

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

The LCM of 190,664,790,456,381 is 1898644920.

Find LCM of 190,664,790,456,381 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 19 x 1 x 83 x 79 x 1 x 127 = 1898644920

Therefore, the lowest common multiple of 190,664,790,456,381 is 1898644920.

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.

190 x 664 x 790 x 456 x 381 = 17315641670400

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.

190 : 1, 2, 5, 10, 19, 38, 95, 190

664 : 1, 2, 4, 8, 83, 166, 332, 664

790 : 1, 2, 5, 10, 79, 158, 395, 790

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,664,790,456,381, is 1.

Now, the common factors can be found like this.

190:2x 5x 19

664:2x 2x 2x 83

790:2x 5x 79

456:2x 2x 2x 3x 19

381:3x 127

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 2x 2x 2x 3x 5x 19 = 9120

Therefore, the value for common factors is 9120.

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 = 17315641670400/(1x9120)

LCM = 17315641670400/9120

LCM = 1898644920

Thus, we can understand that the LCM of 190,664,790,456,381 is 1898644920.
