Given numbers are 257,257,667,386

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

The LCM of 257,257,667,386 is 66167734.

Find LCM of 257,257,667,386 with Prime Factorization

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

257 x 1 x 1 x 667 x 386 = 66167734

Therefore, the lowest common multiple of 257,257,667,386 is 66167734.

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 257 x 667 x 386 = 17005107638

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

257 : 1, 257

667 : 1, 23, 29, 667

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,257,667,386, is 1.

Now, the common factors can be found like this.

257:257

257:257

667:23x 29

386:2x 193

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 = 17005107638/(1x257)

LCM = 17005107638/257

LCM = 66167734

Thus, we can understand that the LCM of 257,257,667,386 is 66167734.
