Given numbers are 422,324,717,156,720

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

The LCM of 422,324,717,156,720 is 4248138960.

Find LCM of 422,324,717,156,720 with Prime Factorization

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

2 x 2 x 3 x 3 x 211 x 9 x 239 x 13 x 20 = 4248138960

Therefore, the lowest common multiple of 422,324,717,156,720 is 4248138960.

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.

422 x 324 x 717 x 156 x 720 = 11011176184320

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.

422 : 1, 2, 211, 422

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

717 : 1, 3, 239, 717

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,324,717,156,720, is 1.

Now, the common factors can be found like this.

422:2x 211

324:2x 2x 3x 3x 3x 3

717:3x 239

156:2x 2x 3x 13

720:2x 2x 2x 2x 3x 3x 5

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 3x 3x 3x 3 = 2592

Therefore, the value for common factors is 2592.

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 = 11011176184320/(1x2592)

LCM = 11011176184320/2592

LCM = 4248138960

Thus, we can understand that the LCM of 422,324,717,156,720 is 4248138960.
