Given numbers are 641,257,974,257

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

The LCM of 641,257,974,257 is 160453838.

Find LCM of 641,257,974,257 with Prime Factorization

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

257 x 641 x 1 x 974 x 1 = 160453838

Therefore, the lowest common multiple of 641,257,974,257 is 160453838.

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.

641 x 257 x 974 x 257 = 41236636366

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.

641 : 1, 641

257 : 1, 257

974 : 1, 2, 487, 974

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,257,974,257, is 1.

Now, the common factors can be found like this.

641:641

257:257

974:2x 487

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 = 41236636366/(1x257)

LCM = 41236636366/257

LCM = 160453838

Thus, we can understand that the LCM of 641,257,974,257 is 160453838.
