Given numbers are 621,982,924,858,663

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

The LCM of 621,982,924,858,663 is 20754681948.

Find LCM of 621,982,924,858,663 with Prime Factorization

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

2 x 3 x 11 x 13 x 207 x 491 x 14 x 1 x 17 = 20754681948

Therefore, the lowest common multiple of 621,982,924,858,663 is 20754681948.

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 982 x 924 x 858 x 663 = 320535308004912

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

982 : 1, 2, 491, 982

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,982,924,858,663, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

982:2x 491

924:2x 2x 3x 7x 11

858:2x 3x 11x 13

663:3x 13x 17

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 3x 3x 3x 11x 13 = 15444

Therefore, the value for common factors is 15444.

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 = 320535308004912/(1x15444)

LCM = 320535308004912/15444

LCM = 20754681948

Thus, we can understand that the LCM of 621,982,924,858,663 is 20754681948.
