Given numbers are 647,138,558,407

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

The LCM of 647,138,558,407 is 3379564386.

Find LCM of 647,138,558,407 with Prime Factorization

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

2 x 3 x 647 x 23 x 93 x 407 = 3379564386

Therefore, the lowest common multiple of 647,138,558,407 is 3379564386.

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.

647 x 138 x 558 x 407 = 20277386316

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.

647 : 1, 647

138 : 1, 2, 3, 6, 23, 46, 69, 138

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,138,558,407, is 1.

Now, the common factors can be found like this.

647:647

138:2x 3x 23

558:2x 3x 3x 31

407:11x 37

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 20277386316/(1x6)

LCM = 20277386316/6

LCM = 3379564386

Thus, we can understand that the LCM of 647,138,558,407 is 3379564386.
