Given numbers are 299,420,641,424

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

The LCM of 299,420,641,424 is 8532658680.

Find LCM of 299,420,641,424 with Prime Factorization

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

2 x 2 x 299 x 105 x 641 x 106 = 8532658680

Therefore, the lowest common multiple of 299,420,641,424 is 8532658680.

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.

299 x 420 x 641 x 424 = 34130634720

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.

299 : 1, 13, 23, 299

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

641 : 1, 641

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 299,420,641,424, is 1.

Now, the common factors can be found like this.

299:13x 23

420:2x 2x 3x 5x 7

641:641

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 = 34130634720/(1x4)

LCM = 34130634720/4

LCM = 8532658680

Thus, we can understand that the LCM of 299,420,641,424 is 8532658680.
