Given numbers are 645,946,932,428,572

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

The LCM of 645,946,932,428,572 is 9198043140.

Find LCM of 645,946,932,428,572 with Prime Factorization

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

2 x 2 x 11 x 43 x 15 x 1 x 233 x 107 x 13 = 9198043140

Therefore, the lowest common multiple of 645,946,932,428,572 is 9198043140.

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.

645 x 946 x 932 x 428 x 572 = 139221580967040

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.

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

946 : 1, 2, 11, 22, 43, 86, 473, 946

932 : 1, 2, 4, 233, 466, 932

428 : 1, 2, 4, 107, 214, 428

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,946,932,428,572, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

946:2x 11x 43

932:2x 2x 233

428:2x 2x 107

572:2x 2x 11x 13

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

2x 2x 2x 2x 2x 11x 43 = 15136

Therefore, the value for common factors is 15136.

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 = 139221580967040/(1x15136)

LCM = 139221580967040/15136

LCM = 9198043140

Thus, we can understand that the LCM of 645,946,932,428,572 is 9198043140.
