Given numbers are 628,692,746,691

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

The LCM of 628,692,746,691 is 28002230492.

Find LCM of 628,692,746,691 with Prime Factorization

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

2 x 2 x 157 x 173 x 373 x 691 = 28002230492

Therefore, the lowest common multiple of 628,692,746,691 is 28002230492.

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 692 x 746 x 691 = 224017843936

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

692 : 1, 2, 4, 173, 346, 692

746 : 1, 2, 373, 746

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,692,746,691, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

692:2x 2x 173

746:2x 373

691:691

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 2 = 8

Therefore, the value for common factors is 8.

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 = 224017843936/(1x8)

LCM = 224017843936/8

LCM = 28002230492

Thus, we can understand that the LCM of 628,692,746,691 is 28002230492.
