Given numbers are 321,715,625,423

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

The LCM of 321,715,625,423 is 4045201875.

Find LCM of 321,715,625,423 with Prime Factorization

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

3 x 5 x 107 x 143 x 125 x 141 = 4045201875

Therefore, the lowest common multiple of 321,715,625,423 is 4045201875.

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.

321 x 715 x 625 x 423 = 60678028125

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.

321 : 1, 3, 107, 321

715 : 1, 5, 11, 13, 55, 65, 143, 715

625 : 1, 5, 25, 125, 625

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,715,625,423, is 1.

Now, the common factors can be found like this.

321:3x 107

715:5x 11x 13

625:5x 5x 5x 5

423:3x 3x 47

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 60678028125/(1x15)

LCM = 60678028125/15

LCM = 4045201875

Thus, we can understand that the LCM of 321,715,625,423 is 4045201875.
