Given numbers are 422,257,771,731

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

The LCM of 422,257,771,731 is 237839622.

Find LCM of 422,257,771,731 with Prime Factorization

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

257 x 422 x 1 x 3 x 731 = 237839622

Therefore, the lowest common multiple of 422,257,771,731 is 237839622.

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 257 x 771 x 731 = 61124782854

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

257 : 1, 257

771 : 1, 3, 257, 771

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,257,771,731, is 1.

Now, the common factors can be found like this.

422:2x 211

257:257

771:3x 257

731:17x 43

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

257 = 257

Therefore, the value for common factors is 257.

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 = 61124782854/(1x257)

LCM = 61124782854/257

LCM = 237839622

Thus, we can understand that the LCM of 422,257,771,731 is 237839622.
