Given numbers are 257,422,842,921

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

The LCM of 257,422,842,921 is 42052062414.

Find LCM of 257,422,842,921 with Prime Factorization

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

2 x 257 x 211 x 421 x 921 = 42052062414

Therefore, the lowest common multiple of 257,422,842,921 is 42052062414.

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.

257 x 422 x 842 x 921 = 84104124828

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.

257 : 1, 257

422 : 1, 2, 211, 422

842 : 1, 2, 421, 842

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,422,842,921, is 1.

Now, the common factors can be found like this.

257:257

422:2x 211

842:2x 421

921:3x 307

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 = 84104124828/(1x2)

LCM = 84104124828/2

LCM = 42052062414

Thus, we can understand that the LCM of 257,422,842,921 is 42052062414.
