Given numbers are 721,805,473,940,630

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

The LCM of 721,805,473,940,630 is 66358201140.

Find LCM of 721,805,473,940,630 with Prime Factorization

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

2 x 5 x 7 x 103 x 23 x 473 x 94 x 9 = 66358201140

Therefore, the lowest common multiple of 721,805,473,940,630 is 66358201140.

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.

721 x 805 x 473 x 940 x 630 = 162577592793000

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.

721 : 1, 7, 103, 721

805 : 1, 5, 7, 23, 35, 115, 161, 805

473 : 1, 11, 43, 473

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,805,473,940,630, is 1.

Now, the common factors can be found like this.

721:7x 103

805:5x 7x 23

473:11x 43

940:2x 2x 5x 47

630:2x 3x 3x 5x 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 5x 5x 7x 7 = 2450

Therefore, the value for common factors is 2450.

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 = 162577592793000/(1x2450)

LCM = 162577592793000/2450

LCM = 66358201140

Thus, we can understand that the LCM of 721,805,473,940,630 is 66358201140.
