Given numbers are 815,422,780,117,163

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

The LCM of 815,422,780,117,163 is 80479620.

Find LCM of 815,422,780,117,163 with Prime Factorization

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

2 x 3 x 5 x 13 x 163 x 1 x 211 x 2 x 3 x 1 = 80479620

Therefore, the lowest common multiple of 815,422,780,117,163 is 80479620.

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.

815 x 422 x 780 x 117 x 163 = 5116089443400

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.

815 : 1, 5, 163, 815

422 : 1, 2, 211, 422

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

117 : 1, 3, 9, 13, 39, 117

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,422,780,117,163, is 1.

Now, the common factors can be found like this.

815:5x 163

422:2x 211

780:2x 2x 3x 5x 13

117:3x 3x 13

163:163

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

2x 3x 5x 13x 163 = 63570

Therefore, the value for common factors is 63570.

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 = 5116089443400/(1x63570)

LCM = 5116089443400/63570

LCM = 80479620

Thus, we can understand that the LCM of 815,422,780,117,163 is 80479620.
