Given numbers are 408,422,211,653

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

The LCM of 408,422,211,653 is 56215464.

Find LCM of 408,422,211,653 with Prime Factorization

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

2 x 211 x 204 x 1 x 1 x 653 = 56215464

Therefore, the lowest common multiple of 408,422,211,653 is 56215464.

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.

408 x 422 x 211 x 653 = 23722925808

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.

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

422 : 1, 2, 211, 422

211 : 1, 211

653 : 1, 653

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,422,211,653, is 1.

Now, the common factors can be found like this.

408:2x 2x 2x 3x 17

422:2x 211

211:211

653:653

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 = 23722925808/(1x422)

LCM = 23722925808/422

LCM = 56215464

Thus, we can understand that the LCM of 408,422,211,653 is 56215464.
