Given numbers are 422,193,752,436,646

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

The LCM of 422,193,752,436,646 is 1078168465072.

Find LCM of 422,193,752,436,646 with Prime Factorization

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

2 x 2 x 211 x 193 x 188 x 109 x 323 = 1078168465072

Therefore, the lowest common multiple of 422,193,752,436,646 is 1078168465072.

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 193 x 752 x 436 x 646 = 17250695441152

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

193 : 1, 193

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

436 : 1, 2, 4, 109, 218, 436

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,193,752,436,646, is 1.

Now, the common factors can be found like this.

422:2x 211

193:193

752:2x 2x 2x 2x 47

436:2x 2x 109

646:2x 17x 19

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 2 = 16

Therefore, the value for common factors is 16.

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 = 17250695441152/(1x16)

LCM = 17250695441152/16

LCM = 1078168465072

Thus, we can understand that the LCM of 422,193,752,436,646 is 1078168465072.
