Given numbers are 764,257,645,257

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

The LCM of 764,257,645,257 is 126644460.

Find LCM of 764,257,645,257 with Prime Factorization

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

257 x 764 x 1 x 645 x 1 = 126644460

Therefore, the lowest common multiple of 764,257,645,257 is 126644460.

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.

764 x 257 x 645 x 257 = 32547626220

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.

764 : 1, 2, 4, 191, 382, 764

257 : 1, 257

645 : 1, 3, 5, 15, 43, 129, 215, 645

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,257,645,257, is 1.

Now, the common factors can be found like this.

764:2x 2x 191

257:257

645:3x 5x 43

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 = 32547626220/(1x257)

LCM = 32547626220/257

LCM = 126644460

Thus, we can understand that the LCM of 764,257,645,257 is 126644460.
