Given numbers are 307,657,221,891,630

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

The LCM of 307,657,221,891,630 is 308908069470.

Find LCM of 307,657,221,891,630 with Prime Factorization

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

3 x 3 x 307 x 73 x 221 x 99 x 70 = 308908069470

Therefore, the lowest common multiple of 307,657,221,891,630 is 308908069470.

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.

307 x 657 x 221 x 891 x 630 = 25021553627070

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.

307 : 1, 307

657 : 1, 3, 9, 73, 219, 657

221 : 1, 13, 17, 221

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

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 307,657,221,891,630, is 1.

Now, the common factors can be found like this.

307:307

657:3x 3x 73

221:13x 17

891:3x 3x 3x 3x 11

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.

3x 3x 3x 3 = 81

Therefore, the value for common factors is 81.

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 = 25021553627070/(1x81)

LCM = 25021553627070/81

LCM = 308908069470

Thus, we can understand that the LCM of 307,657,221,891,630 is 308908069470.
