Given numbers are 869,489,836,660,216

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

The LCM of 869,489,836,660,216 is 2906596440.

Find LCM of 869,489,836,660,216 with Prime Factorization

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

2 x 2 x 3 x 11 x 79 x 163 x 19 x 5 x 18 = 2906596440

Therefore, the lowest common multiple of 869,489,836,660,216 is 2906596440.

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.

869 x 489 x 836 x 660 x 216 = 50644536370560

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.

869 : 1, 11, 79, 869

489 : 1, 3, 163, 489

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

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

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,489,836,660,216, is 1.

Now, the common factors can be found like this.

869:11x 79

489:3x 163

836:2x 2x 11x 19

660:2x 2x 3x 5x 11

216:2x 2x 2x 3x 3x 3

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 3x 3x 11x 11 = 17424

Therefore, the value for common factors is 17424.

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 = 50644536370560/(1x17424)

LCM = 50644536370560/17424

LCM = 2906596440

Thus, we can understand that the LCM of 869,489,836,660,216 is 2906596440.
