Given numbers are 854,731,520,432

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

The LCM of 854,731,520,432 is 8764806960.

Find LCM of 854,731,520,432 with Prime Factorization

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

2 x 2 x 2 x 427 x 731 x 65 x 54 = 8764806960

Therefore, the lowest common multiple of 854,731,520,432 is 8764806960.

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.

854 x 731 x 520 x 432 = 140236911360

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.

854 : 1, 2, 7, 14, 61, 122, 427, 854

731 : 1, 17, 43, 731

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,731,520,432, is 1.

Now, the common factors can be found like this.

854:2x 7x 61

731:17x 43

520:2x 2x 2x 5x 13

432:2x 2x 2x 2x 3x 3x 3

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 = 140236911360/(1x16)

LCM = 140236911360/16

LCM = 8764806960

Thus, we can understand that the LCM of 854,731,520,432 is 8764806960.
