Given numbers are 520,747,393,662

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

The LCM of 520,747,393,662 is 16843146840.

Find LCM of 520,747,393,662 with Prime Factorization

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

2 x 3 x 260 x 249 x 131 x 331 = 16843146840

Therefore, the lowest common multiple of 520,747,393,662 is 16843146840.

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.

520 x 747 x 393 x 662 = 101058881040

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

747 : 1, 3, 9, 83, 249, 747

393 : 1, 3, 131, 393

662 : 1, 2, 331, 662

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,747,393,662, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

747:3x 3x 83

393:3x 131

662:2x 331

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 = 101058881040/(1x6)

LCM = 101058881040/6

LCM = 16843146840

Thus, we can understand that the LCM of 520,747,393,662 is 16843146840.

Here are some samples of LCM of two or more Numbers calculations.
