Given numbers are 257,619,315,257

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

The LCM of 257,619,315,257 is 50111145.

Find LCM of 257,619,315,257 with Prime Factorization

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

257 x 1 x 619 x 315 x 1 = 50111145

Therefore, the lowest common multiple of 257,619,315,257 is 50111145.

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 619 x 315 x 257 = 12878564265

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

619 : 1, 619

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,619,315,257, is 1.

Now, the common factors can be found like this.

257:257

619:619

315:3x 3x 5x 7

257:257

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 = 12878564265/(1x257)

LCM = 12878564265/257

LCM = 50111145

Thus, we can understand that the LCM of 257,619,315,257 is 50111145.
