Given numbers are 437,731,420,328

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

The LCM of 437,731,420,328 is 11001754680.

Find LCM of 437,731,420,328 with Prime Factorization

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

2 x 2 x 437 x 731 x 105 x 82 = 11001754680

Therefore, the lowest common multiple of 437,731,420,328 is 11001754680.

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.

437 x 731 x 420 x 328 = 44007018720

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.

437 : 1, 19, 23, 437

731 : 1, 17, 43, 731

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

328 : 1, 2, 4, 8, 41, 82, 164, 328

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,731,420,328, is 1.

Now, the common factors can be found like this.

437:19x 23

731:17x 43

420:2x 2x 3x 5x 7

328:2x 2x 2x 41

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 = 44007018720/(1x4)

LCM = 44007018720/4

LCM = 11001754680

Thus, we can understand that the LCM of 437,731,420,328 is 11001754680.
