Given numbers are 630,798,418,987

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

The LCM of 630,798,418,987 is 6188490.

Find LCM of 630,798,418,987 with Prime Factorization

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

2 x 3 x 7 x 19 x 15 x 1 x 11 x 47 = 6188490

Therefore, the lowest common multiple of 630,798,418,987 is 6188490.

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 798 x 418 x 987 = 207413430840

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

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

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,798,418,987, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

798:2x 3x 7x 19

418:2x 11x 19

987:3x 7x 47

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 3x 3x 7x 7x 19 = 33516

Therefore, the value for common factors is 33516.

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 = 207413430840/(1x33516)

LCM = 207413430840/33516

LCM = 6188490

Thus, we can understand that the LCM of 630,798,418,987 is 6188490.
