Given numbers are 129,842,622,620

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

The LCM of 129,842,622,620 is 10471861380.

Find LCM of 129,842,622,620 with Prime Factorization

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

2 x 129 x 421 x 311 x 310 = 10471861380

Therefore, the lowest common multiple of 129,842,622,620 is 10471861380.

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.

129 x 842 x 622 x 620 = 41887445520

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.

129 : 1, 3, 43, 129

842 : 1, 2, 421, 842

622 : 1, 2, 311, 622

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,842,622,620, is 1.

Now, the common factors can be found like this.

129:3x 43

842:2x 421

622:2x 311

620:2x 2x 5x 31

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 = 41887445520/(1x4)

LCM = 41887445520/4

LCM = 10471861380

Thus, we can understand that the LCM of 129,842,622,620 is 10471861380.
