Given numbers are 628,928,730,672

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

The LCM of 628,928,730,672 is 1116759840.

Find LCM of 628,928,730,672 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 157 x 29 x 365 x 21 = 1116759840

Therefore, the lowest common multiple of 628,928,730,672 is 1116759840.

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 928 x 730 x 672 = 285890519040

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

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

730 : 1, 2, 5, 10, 73, 146, 365, 730

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,928,730,672, is 2.

Now, the common factors can be found like this.

628:2x 2x 157

928:2x 2x 2x 2x 2x 29

730:2x 5x 73

672:2x 2x 2x 2x 2x 3x 7

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 2x 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 285890519040/(2x128)

LCM = 285890519040/256

LCM = 1116759840

Thus, we can understand that the LCM of 628,928,730,672 is 1116759840.
