Given numbers are 813,566,516,420

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

The LCM of 813,566,516,420 is 1385075580.

Find LCM of 813,566,516,420 with Prime Factorization

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

2 x 2 x 3 x 271 x 283 x 43 x 35 = 1385075580

Therefore, the lowest common multiple of 813,566,516,420 is 1385075580.

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.

813 x 566 x 516 x 420 = 99725441760

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.

813 : 1, 3, 271, 813

566 : 1, 2, 283, 566

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,566,516,420, is 1.

Now, the common factors can be found like this.

813:3x 271

566:2x 283

516:2x 2x 3x 43

420:2x 2x 3x 5x 7

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 99725441760/(1x72)

LCM = 99725441760/72

LCM = 1385075580

Thus, we can understand that the LCM of 813,566,516,420 is 1385075580.
