Given numbers are 717,842,420,832

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

The LCM of 717,842,420,832 is 8790075840.

Find LCM of 717,842,420,832 with Prime Factorization

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

2 x 2 x 3 x 239 x 421 x 35 x 208 = 8790075840

Therefore, the lowest common multiple of 717,842,420,832 is 8790075840.

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.

717 x 842 x 420 x 832 = 210961820160

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.

717 : 1, 3, 239, 717

842 : 1, 2, 421, 842

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,842,420,832, is 1.

Now, the common factors can be found like this.

717:3x 239

842:2x 421

420:2x 2x 3x 5x 7

832:2x 2x 2x 2x 2x 2x 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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 210961820160/(1x24)

LCM = 210961820160/24

LCM = 8790075840

Thus, we can understand that the LCM of 717,842,420,832 is 8790075840.
