Given numbers are 621,709,860,404

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

The LCM of 621,709,860,404 is 38243502540.

Find LCM of 621,709,860,404 with Prime Factorization

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

2 x 2 x 621 x 709 x 215 x 101 = 38243502540

Therefore, the lowest common multiple of 621,709,860,404 is 38243502540.

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.

621 x 709 x 860 x 404 = 152974010160

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.

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

709 : 1, 709

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,709,860,404, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

709:709

860:2x 2x 5x 43

404:2x 2x 101

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 152974010160/(1x4)

LCM = 152974010160/4

LCM = 38243502540

Thus, we can understand that the LCM of 621,709,860,404 is 38243502540.
