Given numbers are 516,420,186,663,386

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

The LCM of 516,420,186,663,386 is 23879708580.

Find LCM of 516,420,186,663,386 with Prime Factorization

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

2 x 2 x 3 x 43 x 35 x 31 x 221 x 193 = 23879708580

Therefore, the lowest common multiple of 516,420,186,663,386 is 23879708580.

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.

516 x 420 x 186 x 663 x 386 = 10316034106560

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.

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

186 : 1, 2, 3, 6, 31, 62, 93, 186

663 : 1, 3, 13, 17, 39, 51, 221, 663

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,420,186,663,386, is 1.

Now, the common factors can be found like this.

516:2x 2x 3x 43

420:2x 2x 3x 5x 7

186:2x 3x 31

663:3x 13x 17

386:2x 193

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 3x 3x 3 = 432

Therefore, the value for common factors is 432.

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 = 10316034106560/(1x432)

LCM = 10316034106560/432

LCM = 23879708580

Thus, we can understand that the LCM of 516,420,186,663,386 is 23879708580.
