Given numbers are 836,409,207,864,455

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

The LCM of 836,409,207,864,455 is 772898686560.

Find LCM of 836,409,207,864,455 with Prime Factorization

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

2 x 2 x 3 x 3 x 209 x 409 x 23 x 24 x 455 = 772898686560

Therefore, the lowest common multiple of 836,409,207,864,455 is 772898686560.

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.

836 x 409 x 207 x 864 x 455 = 27824352716160

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.

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

409 : 1, 409

207 : 1, 3, 9, 23, 69, 207

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,409,207,864,455, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

409:409

207:3x 3x 23

864:2x 2x 2x 2x 2x 3x 3x 3

455:5x 7x 13

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 3 = 36

Therefore, the value for common factors is 36.

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 = 27824352716160/(1x36)

LCM = 27824352716160/36

LCM = 772898686560

Thus, we can understand that the LCM of 836,409,207,864,455 is 772898686560.
