Given numbers are 638,436,722,554

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

The LCM of 638,436,722,554 is 13907982748.

Find LCM of 638,436,722,554 with Prime Factorization

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

2 x 319 x 218 x 361 x 277 = 13907982748

Therefore, the lowest common multiple of 638,436,722,554 is 13907982748.

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 436 x 722 x 554 = 111263861984

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

436 : 1, 2, 4, 109, 218, 436

722 : 1, 2, 19, 38, 361, 722

554 : 1, 2, 277, 554

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,436,722,554, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

436:2x 2x 109

722:2x 19x 19

554:2x 277

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 = 111263861984/(2x4)

LCM = 111263861984/8

LCM = 13907982748

Thus, we can understand that the LCM of 638,436,722,554 is 13907982748.
