Given numbers are 730,713,643,398

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

The LCM of 730,713,643,398 is 66600338930.

Find LCM of 730,713,643,398 with Prime Factorization

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

2 x 365 x 713 x 643 x 199 = 66600338930

Therefore, the lowest common multiple of 730,713,643,398 is 66600338930.

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.

730 x 713 x 643 x 398 = 133200677860

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.

730 : 1, 2, 5, 10, 73, 146, 365, 730

713 : 1, 23, 31, 713

643 : 1, 643

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,713,643,398, is 1.

Now, the common factors can be found like this.

730:2x 5x 73

713:23x 31

643:643

398:2x 199

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

2 = 2

Therefore, the value for common factors is 2.

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 = 133200677860/(1x2)

LCM = 133200677860/2

LCM = 66600338930

Thus, we can understand that the LCM of 730,713,643,398 is 66600338930.
