Given numbers are 305,671,128,836

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

The LCM of 305,671,128,836 is 8159360.

Find LCM of 305,671,128,836 with Prime Factorization

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

2 x 2 x 11 x 61 x 5 x 1 x 32 x 19 = 8159360

Therefore, the lowest common multiple of 305,671,128,836 is 8159360.

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.

305 x 671 x 128 x 836 = 21899722240

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.

305 : 1, 5, 61, 305

671 : 1, 11, 61, 671

128 : 1, 2, 4, 8, 16, 32, 64, 128

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,671,128,836, is 1.

Now, the common factors can be found like this.

305:5x 61

671:11x 61

128:2x 2x 2x 2x 2x 2x 2

836:2x 2x 11x 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 11x 61 = 2684

Therefore, the value for common factors is 2684.

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 = 21899722240/(1x2684)

LCM = 21899722240/2684

LCM = 8159360

Thus, we can understand that the LCM of 305,671,128,836 is 8159360.
