Given numbers are 406,644,621,511,708

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

The LCM of 406,644,621,511,708 is 2171813364.

Find LCM of 406,644,621,511,708 with Prime Factorization

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

2 x 2 x 3 x 7 x 23 x 29 x 1 x 9 x 73 x 59 = 2171813364

Therefore, the lowest common multiple of 406,644,621,511,708 is 2171813364.

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.

406 x 644 x 621 x 511 x 708 = 58743207869472

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

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

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

511 : 1, 7, 73, 511

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,644,621,511,708, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

644:2x 2x 7x 23

621:3x 3x 3x 23

511:7x 73

708:2x 2x 3x 59

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 3x 7x 7x 23 = 27048

Therefore, the value for common factors is 27048.

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 = 58743207869472/(1x27048)

LCM = 58743207869472/27048

LCM = 2171813364

Thus, we can understand that the LCM of 406,644,621,511,708 is 2171813364.
