Given numbers are 173,865,686,128

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

The LCM of 173,865,686,128 is 37976960.

Find LCM of 173,865,686,128 with Prime Factorization

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

2 x 173 x 1 x 5 x 343 x 64 = 37976960

Therefore, the lowest common multiple of 173,865,686,128 is 37976960.

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.

173 x 865 x 686 x 128 = 13140028160

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.

173 : 1, 173

865 : 1, 5, 173, 865

686 : 1, 2, 7, 14, 49, 98, 343, 686

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,865,686,128, is 1.

Now, the common factors can be found like this.

173:173

865:5x 173

686:2x 7x 7x 7

128:2x 2x 2x 2x 2x 2x 2

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

2x 173 = 346

Therefore, the value for common factors is 346.

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 = 13140028160/(1x346)

LCM = 13140028160/346

LCM = 37976960

Thus, we can understand that the LCM of 173,865,686,128 is 37976960.
