Given numbers are 763,842,170,656

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

The LCM of 763,842,170,656 is 17911394480.

Find LCM of 763,842,170,656 with Prime Factorization

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

2 x 763 x 421 x 85 x 328 = 17911394480

Therefore, the lowest common multiple of 763,842,170,656 is 17911394480.

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.

763 x 842 x 170 x 656 = 71645577920

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.

763 : 1, 7, 109, 763

842 : 1, 2, 421, 842

170 : 1, 2, 5, 10, 17, 34, 85, 170

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,842,170,656, is 1.

Now, the common factors can be found like this.

763:7x 109

842:2x 421

170:2x 5x 17

656:2x 2x 2x 2x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 71645577920/(1x4)

LCM = 71645577920/4

LCM = 17911394480

Thus, we can understand that the LCM of 763,842,170,656 is 17911394480.
