Given numbers are 422,195,418,647

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

The LCM of 422,195,418,647 is 11127500670.

Find LCM of 422,195,418,647 with Prime Factorization

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

2 x 211 x 195 x 209 x 647 = 11127500670

Therefore, the lowest common multiple of 422,195,418,647 is 11127500670.

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 195 x 418 x 647 = 22255001340

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

195 : 1, 3, 5, 13, 15, 39, 65, 195

418 : 1, 2, 11, 19, 22, 38, 209, 418

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,195,418,647, is 1.

Now, the common factors can be found like this.

422:2x 211

195:3x 5x 13

418:2x 11x 19

647:647

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 22255001340/(1x2)

LCM = 22255001340/2

LCM = 11127500670

Thus, we can understand that the LCM of 422,195,418,647 is 11127500670.
