Given numbers are 787,644,730,621

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

The LCM of 787,644,730,621 is 4994789940.

Find LCM of 787,644,730,621 with Prime Factorization

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

2 x 23 x 787 x 14 x 365 x 27 = 4994789940

Therefore, the lowest common multiple of 787,644,730,621 is 4994789940.

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.

787 x 644 x 730 x 621 = 229760337240

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.

787 : 1, 787

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,644,730,621, is 1.

Now, the common factors can be found like this.

787:787

644:2x 2x 7x 23

730:2x 5x 73

621:3x 3x 3x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 229760337240/(1x46)

LCM = 229760337240/46

LCM = 4994789940

Thus, we can understand that the LCM of 787,644,730,621 is 4994789940.
