Given numbers are 257,257,771,806

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

The LCM of 257,257,771,806 is 621426.

Find LCM of 257,257,771,806 with Prime Factorization

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

257 x 1 x 1 x 3 x 806 = 621426

Therefore, the lowest common multiple of 257,257,771,806 is 621426.

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 771 x 806 = 41044565874

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

771 : 1, 3, 257, 771

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,257,771,806, is 1.

Now, the common factors can be found like this.

257:257

257:257

771:3x 257

806:2x 13x 31

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

257x 257 = 66049

Therefore, the value for common factors is 66049.

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 = 41044565874/(1x66049)

LCM = 41044565874/66049

LCM = 621426

Thus, we can understand that the LCM of 257,257,771,806 is 621426.
