Given numbers are 422,646,273,756,554

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

The LCM of 422,646,273,756,554 is 185536728468.

Find LCM of 422,646,273,756,554 with Prime Factorization

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

2 x 3 x 7 x 211 x 323 x 13 x 18 x 277 = 185536728468

Therefore, the lowest common multiple of 422,646,273,756,554 is 185536728468.

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 646 x 273 x 756 x 554 = 31170170382624

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

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,646,273,756,554, is 1.

Now, the common factors can be found like this.

422:2x 211

646:2x 17x 19

273:3x 7x 13

756:2x 2x 3x 3x 3x 7

554:2x 277

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 3x 7 = 168

Therefore, the value for common factors is 168.

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 = 31170170382624/(1x168)

LCM = 31170170382624/168

LCM = 185536728468

Thus, we can understand that the LCM of 422,646,273,756,554 is 185536728468.
