Given numbers are 257,572,821,278

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

The LCM of 257,572,821,278 is 16775949476.

Find LCM of 257,572,821,278 with Prime Factorization

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

2 x 257 x 286 x 821 x 139 = 16775949476

Therefore, the lowest common multiple of 257,572,821,278 is 16775949476.

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 572 x 821 x 278 = 33551898952

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

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

821 : 1, 821

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,572,821,278, is 1.

Now, the common factors can be found like this.

257:257

572:2x 2x 11x 13

821:821

278:2x 139

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 = 33551898952/(1x2)

LCM = 33551898952/2

LCM = 16775949476

Thus, we can understand that the LCM of 257,572,821,278 is 16775949476.
