Given numbers are 638,226,997,506

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

The LCM of 638,226,997,506 is 1653187514.

Find LCM of 638,226,997,506 with Prime Factorization

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

2 x 11 x 29 x 113 x 997 x 23 = 1653187514

Therefore, the lowest common multiple of 638,226,997,506 is 1653187514.

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 226 x 997 x 506 = 72740250616

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

226 : 1, 2, 113, 226

997 : 1, 997

506 : 1, 2, 11, 22, 23, 46, 253, 506

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,226,997,506, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

226:2x 113

997:997

506:2x 11x 23

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 11 = 44

Therefore, the value for common factors is 44.

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 = 72740250616/(1x44)

LCM = 72740250616/44

LCM = 1653187514

Thus, we can understand that the LCM of 638,226,997,506 is 1653187514.
