Given numbers are 392,408,902,863

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

The LCM of 392,408,902,863 is 7781146296.

Find LCM of 392,408,902,863 with Prime Factorization

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

2 x 2 x 2 x 49 x 51 x 451 x 863 = 7781146296

Therefore, the lowest common multiple of 392,408,902,863 is 7781146296.

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.

392 x 408 x 902 x 863 = 124498340736

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

902 : 1, 2, 11, 22, 41, 82, 451, 902

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,408,902,863, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

408:2x 2x 2x 3x 17

902:2x 11x 41

863:863

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 2 = 16

Therefore, the value for common factors is 16.

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 = 124498340736/(1x16)

LCM = 124498340736/16

LCM = 7781146296

Thus, we can understand that the LCM of 392,408,902,863 is 7781146296.
