Given numbers are 422,154,452,638

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

The LCM of 422,154,452,638 is 212965676.

Find LCM of 422,154,452,638 with Prime Factorization

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

2 x 11 x 211 x 7 x 226 x 29 = 212965676

Therefore, the lowest common multiple of 422,154,452,638 is 212965676.

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 154 x 452 x 638 = 18740979488

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

154 : 1, 2, 7, 11, 14, 22, 77, 154

452 : 1, 2, 4, 113, 226, 452

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,154,452,638, is 2.

Now, the common factors can be found like this.

422:2x 211

154:2x 7x 11

452:2x 2x 113

638:2x 11x 29

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 11 = 44

Therefore, the value for common factors is 44.

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 = 18740979488/(2x44)

LCM = 18740979488/88

LCM = 212965676

Thus, we can understand that the LCM of 422,154,452,638 is 212965676.
