Given numbers are 832,990,122,857

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

The LCM of 832,990,122,857 is 21529759680.

Find LCM of 832,990,122,857 with Prime Factorization

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

2 x 416 x 495 x 61 x 857 = 21529759680

Therefore, the lowest common multiple of 832,990,122,857 is 21529759680.

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.

832 x 990 x 122 x 857 = 86119038720

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.

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

122 : 1, 2, 61, 122

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,990,122,857, is 1.

Now, the common factors can be found like this.

832:2x 2x 2x 2x 2x 2x 13

990:2x 3x 3x 5x 11

122:2x 61

857:857

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 86119038720/(1x4)

LCM = 86119038720/4

LCM = 21529759680

Thus, we can understand that the LCM of 832,990,122,857 is 21529759680.
