Given numbers are 863,638,436,716

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

The LCM of 863,638,436,716 is 21485279068.

Find LCM of 863,638,436,716 with Prime Factorization

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

2 x 2 x 863 x 319 x 109 x 179 = 21485279068

Therefore, the lowest common multiple of 863,638,436,716 is 21485279068.

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.

863 x 638 x 436 x 716 = 171882232544

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.

863 : 1, 863

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

436 : 1, 2, 4, 109, 218, 436

716 : 1, 2, 4, 179, 358, 716

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,638,436,716, is 1.

Now, the common factors can be found like this.

863:863

638:2x 11x 29

436:2x 2x 109

716:2x 2x 179

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 2 = 8

Therefore, the value for common factors is 8.

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 = 171882232544/(1x8)

LCM = 171882232544/8

LCM = 21485279068

Thus, we can understand that the LCM of 863,638,436,716 is 21485279068.
