Given numbers are 418,643,442,514

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

The LCM of 418,643,442,514 is 15265556878.

Find LCM of 418,643,442,514 with Prime Factorization

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

2 x 209 x 643 x 221 x 257 = 15265556878

Therefore, the lowest common multiple of 418,643,442,514 is 15265556878.

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 643 x 442 x 514 = 61062227512

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

643 : 1, 643

442 : 1, 2, 13, 17, 26, 34, 221, 442

514 : 1, 2, 257, 514

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,643,442,514, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

643:643

442:2x 13x 17

514:2x 257

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 = 61062227512/(1x4)

LCM = 61062227512/4

LCM = 15265556878

Thus, we can understand that the LCM of 418,643,442,514 is 15265556878.
