Given numbers are 630,722,654,911,257

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

The LCM of 630,722,654,911,257 is 5803977893490.

Find LCM of 630,722,654,911,257 with Prime Factorization

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

2 x 3 x 105 x 361 x 109 x 911 x 257 = 5803977893490

Therefore, the lowest common multiple of 630,722,654,911,257 is 5803977893490.

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.

630 x 722 x 654 x 911 x 257 = 69647734721880

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

722 : 1, 2, 19, 38, 361, 722

654 : 1, 2, 3, 6, 109, 218, 327, 654

911 : 1, 911

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,722,654,911,257, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

722:2x 19x 19

654:2x 3x 109

911:911

257:257

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 69647734721880/(1x12)

LCM = 69647734721880/12

LCM = 5803977893490

Thus, we can understand that the LCM of 630,722,654,911,257 is 5803977893490.
