Given numbers are 418,386,411,817

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

The LCM of 418,386,411,817 is 1425751602.

Find LCM of 418,386,411,817 with Prime Factorization

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

2 x 19 x 11 x 193 x 411 x 43 = 1425751602

Therefore, the lowest common multiple of 418,386,411,817 is 1425751602.

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.

418 x 386 x 411 x 817 = 54178560876

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

386 : 1, 2, 193, 386

411 : 1, 3, 137, 411

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,386,411,817, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

386:2x 193

411:3x 137

817:19x 43

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 54178560876/(1x38)

LCM = 54178560876/38

LCM = 1425751602

Thus, we can understand that the LCM of 418,386,411,817 is 1425751602.
