Given numbers are 646,185,399,493

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

The LCM of 646,185,399,493 is 72781590.

Find LCM of 646,185,399,493 with Prime Factorization

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

17 x 19 x 2 x 185 x 21 x 29 = 72781590

Therefore, the lowest common multiple of 646,185,399,493 is 72781590.

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.

646 x 185 x 399 x 493 = 23508453570

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

185 : 1, 5, 37, 185

399 : 1, 3, 7, 19, 21, 57, 133, 399

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,185,399,493, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

185:5x 37

399:3x 7x 19

493:17x 29

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

17x 19 = 323

Therefore, the value for common factors is 323.

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 = 23508453570/(1x323)

LCM = 23508453570/323

LCM = 72781590

Thus, we can understand that the LCM of 646,185,399,493 is 72781590.
