Given numbers are 422,561,422,205

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

The LCM of 422,561,422,205 is 48532110.

Find LCM of 422,561,422,205 with Prime Factorization

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

2 x 211 x 1 x 561 x 1 x 205 = 48532110

Therefore, the lowest common multiple of 422,561,422,205 is 48532110.

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 561 x 422 x 205 = 20480550420

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

561 : 1, 3, 11, 17, 33, 51, 187, 561

422 : 1, 2, 211, 422

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,561,422,205, is 1.

Now, the common factors can be found like this.

422:2x 211

561:3x 11x 17

422:2x 211

205:5x 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 211 = 422

Therefore, the value for common factors is 422.

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 = 20480550420/(1x422)

LCM = 20480550420/422

LCM = 48532110

Thus, we can understand that the LCM of 422,561,422,205 is 48532110.
