Given numbers are 643,606,307,505

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

The LCM of 643,606,307,505 is 598125030.

Find LCM of 643,606,307,505 with Prime Factorization

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

101 x 643 x 6 x 307 x 5 = 598125030

Therefore, the lowest common multiple of 643,606,307,505 is 598125030.

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.

643 x 606 x 307 x 505 = 60410628030

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.

643 : 1, 643

606 : 1, 2, 3, 6, 101, 202, 303, 606

307 : 1, 307

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,606,307,505, is 1.

Now, the common factors can be found like this.

643:643

606:2x 3x 101

307:307

505:5x 101

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

101 = 101

Therefore, the value for common factors is 101.

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 = 60410628030/(1x101)

LCM = 60410628030/101

LCM = 598125030

Thus, we can understand that the LCM of 643,606,307,505 is 598125030.
