Given numbers are 842,676,988,448,660

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

The LCM of 842,676,988,448,660 is 99927347520.

Find LCM of 842,676,988,448,660 with Prime Factorization

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

2 x 2 x 13 x 421 x 13 x 19 x 112 x 165 = 99927347520

Therefore, the lowest common multiple of 842,676,988,448,660 is 99927347520.

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.

842 x 676 x 988 x 448 x 660 = 166279106273280

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.

842 : 1, 2, 421, 842

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,676,988,448,660, is 2.

Now, the common factors can be found like this.

842:2x 421

676:2x 2x 13x 13

988:2x 2x 13x 19

448:2x 2x 2x 2x 2x 2x 7

660:2x 2x 3x 5x 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 2x 2x 2x 2x 13 = 832

Therefore, the value for common factors is 832.

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 = 166279106273280/(2x832)

LCM = 166279106273280/1664

LCM = 99927347520

Thus, we can understand that the LCM of 842,676,988,448,660 is 99927347520.
