Given numbers are 457,914,645,217

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

The LCM of 457,914,645,217 is 127928010.

Find LCM of 457,914,645,217 with Prime Factorization

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

457 x 1 x 2 x 645 x 217 = 127928010

Therefore, the lowest common multiple of 457,914,645,217 is 127928010.

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.

457 x 914 x 645 x 217 = 58463100570

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.

457 : 1, 457

914 : 1, 2, 457, 914

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

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,914,645,217, is 1.

Now, the common factors can be found like this.

457:457

914:2x 457

645:3x 5x 43

217:7x 31

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

457 = 457

Therefore, the value for common factors is 457.

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 = 58463100570/(1x457)

LCM = 58463100570/457

LCM = 127928010

Thus, we can understand that the LCM of 457,914,645,217 is 127928010.
