Given numbers are 863,842,484,652,721

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

The LCM of 863,842,484,652,721 is 20666223521636.

Find LCM of 863,842,484,652,721 with Prime Factorization

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

2 x 2 x 863 x 421 x 121 x 163 x 721 = 20666223521636

Therefore, the lowest common multiple of 863,842,484,652,721 is 20666223521636.

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 842 x 484 x 652 x 721 = 165329788173088

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

842 : 1, 2, 421, 842

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

652 : 1, 2, 4, 163, 326, 652

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,842,484,652,721, is 1.

Now, the common factors can be found like this.

863:863

842:2x 421

484:2x 2x 11x 11

652:2x 2x 163

721:7x 103

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 = 165329788173088/(1x8)

LCM = 165329788173088/8

LCM = 20666223521636

Thus, we can understand that the LCM of 863,842,484,652,721 is 20666223521636.
