Given numbers are 638,812,623,177

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

The LCM of 638,812,623,177 is 140705796.

Find LCM of 638,812,623,177 with Prime Factorization

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

2 x 7 x 29 x 11 x 2 x 89 x 177 = 140705796

Therefore, the lowest common multiple of 638,812,623,177 is 140705796.

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.

638 x 812 x 623 x 177 = 57126553176

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

623 : 1, 7, 89, 623

177 : 1, 3, 59, 177

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,812,623,177, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

812:2x 2x 7x 29

623:7x 89

177:3x 59

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

2x 7x 29 = 406

Therefore, the value for common factors is 406.

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 = 57126553176/(1x406)

LCM = 57126553176/406

LCM = 140705796

Thus, we can understand that the LCM of 638,812,623,177 is 140705796.
