Given numbers are 628,544,554,602,643

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

The LCM of 628,544,554,602,643 is 4578843390688.

Find LCM of 628,544,554,602,643 with Prime Factorization

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

2 x 2 x 157 x 136 x 277 x 301 x 643 = 4578843390688

Therefore, the lowest common multiple of 628,544,554,602,643 is 4578843390688.

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.

628 x 544 x 554 x 602 x 643 = 73261494251008

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.

628 : 1, 2, 4, 157, 314, 628

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

554 : 1, 2, 277, 554

602 : 1, 2, 7, 14, 43, 86, 301, 602

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,544,554,602,643, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

544:2x 2x 2x 2x 2x 17

554:2x 277

602:2x 7x 43

643:643

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 2 = 16

Therefore, the value for common factors is 16.

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 = 73261494251008/(1x16)

LCM = 73261494251008/16

LCM = 4578843390688

Thus, we can understand that the LCM of 628,544,554,602,643 is 4578843390688.
