Given numbers are 129,260,790,838

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

The LCM of 129,260,790,838 is 1110207540.

Find LCM of 129,260,790,838 with Prime Factorization

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

2 x 5 x 129 x 26 x 79 x 419 = 1110207540

Therefore, the lowest common multiple of 129,260,790,838 is 1110207540.

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 260 x 790 x 838 = 22204150800

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

790 : 1, 2, 5, 10, 79, 158, 395, 790

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,260,790,838, is 1.

Now, the common factors can be found like this.

129:3x 43

260:2x 2x 5x 13

790:2x 5x 79

838:2x 419

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 5 = 20

Therefore, the value for common factors is 20.

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 = 22204150800/(1x20)

LCM = 22204150800/20

LCM = 1110207540

Thus, we can understand that the LCM of 129,260,790,838 is 1110207540.
