Given numbers are 642,893,666,630

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

The LCM of 642,893,666,630 is 2227293810.

Find LCM of 642,893,666,630 with Prime Factorization

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

2 x 3 x 3 x 107 x 893 x 37 x 35 = 2227293810

Therefore, the lowest common multiple of 642,893,666,630 is 2227293810.

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.

642 x 893 x 666 x 630 = 240547731480

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

893 : 1, 19, 47, 893

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,893,666,630, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

893:19x 47

666:2x 3x 3x 37

630:2x 3x 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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 240547731480/(1x108)

LCM = 240547731480/108

LCM = 2227293810

Thus, we can understand that the LCM of 642,893,666,630 is 2227293810.
