Given numbers are 121,951,585,840,396

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

The LCM of 121,951,585,840,396 is 1256575320.

Find LCM of 121,951,585,840,396 with Prime Factorization

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

2 x 2 x 3 x 3 x 5 x 11 x 1 x 317 x 13 x 14 x 11 = 1256575320

Therefore, the lowest common multiple of 121,951,585,840,396 is 1256575320.

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.

121 x 951 x 585 x 840 x 396 = 22392172202400

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.

121 : 1, 11, 121

951 : 1, 3, 317, 951

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,951,585,840,396, is 1.

Now, the common factors can be found like this.

121:11x 11

951:3x 317

585:3x 3x 5x 13

840:2x 2x 2x 3x 5x 7

396:2x 2x 3x 3x 11

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 3x 5x 11 = 17820

Therefore, the value for common factors is 17820.

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 = 22392172202400/(1x17820)

LCM = 22392172202400/17820

LCM = 1256575320

Thus, we can understand that the LCM of 121,951,585,840,396 is 1256575320.
