Given numbers are 623,623,790,643

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

The LCM of 623,623,790,643 is 316465310.

Find LCM of 623,623,790,643 with Prime Factorization

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

7 x 89 x 1 x 1 x 790 x 643 = 316465310

Therefore, the lowest common multiple of 623,623,790,643 is 316465310.

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.

623 x 623 x 790 x 643 = 197157888130

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.

623 : 1, 7, 89, 623

623 : 1, 7, 89, 623

790 : 1, 2, 5, 10, 79, 158, 395, 790

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,623,790,643, is 1.

Now, the common factors can be found like this.

623:7x 89

623:7x 89

790:2x 5x 79

643:643

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

7x 89 = 623

Therefore, the value for common factors is 623.

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 = 197157888130/(1x623)

LCM = 197157888130/623

LCM = 316465310

Thus, we can understand that the LCM of 623,623,790,643 is 316465310.
