Given numbers are 747,387,687,619

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

The LCM of 747,387,687,619 is 4553183871.

Find LCM of 747,387,687,619 with Prime Factorization

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

3 x 3 x 83 x 43 x 229 x 619 = 4553183871

Therefore, the lowest common multiple of 747,387,687,619 is 4553183871.

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.

747 x 387 x 687 x 619 = 122935964517

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.

747 : 1, 3, 9, 83, 249, 747

387 : 1, 3, 9, 43, 129, 387

687 : 1, 3, 229, 687

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,387,687,619, is 1.

Now, the common factors can be found like this.

747:3x 3x 83

387:3x 3x 43

687:3x 229

619:619

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 122935964517/(1x27)

LCM = 122935964517/27

LCM = 4553183871

Thus, we can understand that the LCM of 747,387,687,619 is 4553183871.
