Given numbers are 555,106,686,638

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

The LCM of 555,106,686,638 is 6437002110.

Find LCM of 555,106,686,638 with Prime Factorization

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

2 x 555 x 53 x 343 x 319 = 6437002110

Therefore, the lowest common multiple of 555,106,686,638 is 6437002110.

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.

555 x 106 x 686 x 638 = 25748008440

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.

555 : 1, 3, 5, 15, 37, 111, 185, 555

106 : 1, 2, 53, 106

686 : 1, 2, 7, 14, 49, 98, 343, 686

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,106,686,638, is 1.

Now, the common factors can be found like this.

555:3x 5x 37

106:2x 53

686:2x 7x 7x 7

638:2x 11x 29

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 = 25748008440/(1x4)

LCM = 25748008440/4

LCM = 6437002110

Thus, we can understand that the LCM of 555,106,686,638 is 6437002110.
