Given numbers are 638,606,434,847,798

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

The LCM of 638,606,434,847,798 is 8767369842.

Find LCM of 638,606,434,847,798 with Prime Factorization

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

2 x 3 x 7 x 11 x 29 x 101 x 31 x 11 x 19 = 8767369842

Therefore, the lowest common multiple of 638,606,434,847,798 is 8767369842.

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.

638 x 606 x 434 x 847 x 798 = 113414696276112

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

606 : 1, 2, 3, 6, 101, 202, 303, 606

434 : 1, 2, 7, 14, 31, 62, 217, 434

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,606,434,847,798, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

606:2x 3x 101

434:2x 7x 31

847:7x 11x 11

798:2x 3x 7x 19

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 7x 7x 11 = 12936

Therefore, the value for common factors is 12936.

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 = 113414696276112/(1x12936)

LCM = 113414696276112/12936

LCM = 8767369842

Thus, we can understand that the LCM of 638,606,434,847,798 is 8767369842.
