Given numbers are 878,209,422,422

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

The LCM of 878,209,422,422 is 38718922.

Find LCM of 878,209,422,422 with Prime Factorization

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

2 x 211 x 439 x 209 x 1 x 1 = 38718922

Therefore, the lowest common multiple of 878,209,422,422 is 38718922.

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.

878 x 209 x 422 x 422 = 32678770168

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.

878 : 1, 2, 439, 878

209 : 1, 11, 19, 209

422 : 1, 2, 211, 422

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,209,422,422, is 1.

Now, the common factors can be found like this.

878:2x 439

209:11x 19

422:2x 211

422:2x 211

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 211 = 844

Therefore, the value for common factors is 844.

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 = 32678770168/(1x844)

LCM = 32678770168/844

LCM = 38718922

Thus, we can understand that the LCM of 878,209,422,422 is 38718922.
