Given numbers are 641,847,636,630

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

The LCM of 641,847,636,630 is 5179523580.

Find LCM of 641,847,636,630 with Prime Factorization

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

2 x 3 x 7 x 641 x 121 x 106 x 15 = 5179523580

Therefore, the lowest common multiple of 641,847,636,630 is 5179523580.

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.

641 x 847 x 636 x 630 = 217539990360

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.

641 : 1, 641

847 : 1, 7, 11, 77, 121, 847

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

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 641,847,636,630, is 1.

Now, the common factors can be found like this.

641:641

847:7x 11x 11

636:2x 2x 3x 53

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 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 217539990360/(1x42)

LCM = 217539990360/42

LCM = 5179523580

Thus, we can understand that the LCM of 641,847,636,630 is 5179523580.
