Given numbers are 638,812,212,257,550

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

The LCM of 638,812,212,257,550 is 3041569300.

Find LCM of 638,812,212,257,550 with Prime Factorization

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

2 x 2 x 11 x 29 x 1 x 7 x 53 x 257 x 25 = 3041569300

Therefore, the lowest common multiple of 638,812,212,257,550 is 3041569300.

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 212 x 257 x 550 = 15524169707200

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

212 : 1, 2, 4, 53, 106, 212

257 : 1, 257

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,812,212,257,550, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

812:2x 2x 7x 29

212:2x 2x 53

257:257

550:2x 5x 5x 11

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 2x 2x 11x 29 = 5104

Therefore, the value for common factors is 5104.

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 = 15524169707200/(1x5104)

LCM = 15524169707200/5104

LCM = 3041569300

Thus, we can understand that the LCM of 638,812,212,257,550 is 3041569300.
