Given numbers are 641,358,766,424

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

The LCM of 641,358,766,424 is 18632695688.

Find LCM of 641,358,766,424 with Prime Factorization

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

2 x 641 x 179 x 383 x 212 = 18632695688

Therefore, the lowest common multiple of 641,358,766,424 is 18632695688.

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.

641 x 358 x 766 x 424 = 74530782752

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.

641 : 1, 641

358 : 1, 2, 179, 358

766 : 1, 2, 383, 766

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,358,766,424, is 1.

Now, the common factors can be found like this.

641:641

358:2x 179

766:2x 383

424:2x 2x 2x 53

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 74530782752/(1x4)

LCM = 74530782752/4

LCM = 18632695688

Thus, we can understand that the LCM of 641,358,766,424 is 18632695688.
