Given numbers are 707,720,331,520

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

The LCM of 707,720,331,520 is 2190399120.

Find LCM of 707,720,331,520 with Prime Factorization

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

2 x 2 x 2 x 5 x 707 x 18 x 331 x 13 = 2190399120

Therefore, the lowest common multiple of 707,720,331,520 is 2190399120.

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.

707 x 720 x 331 x 520 = 87615964800

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.

707 : 1, 7, 101, 707

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

331 : 1, 331

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,720,331,520, is 1.

Now, the common factors can be found like this.

707:7x 101

720:2x 2x 2x 2x 3x 3x 5

331:331

520:2x 2x 2x 5x 13

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

2x 2x 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 87615964800/(1x40)

LCM = 87615964800/40

LCM = 2190399120

Thus, we can understand that the LCM of 707,720,331,520 is 2190399120.
