Given numbers are 520,806,528,621

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

The LCM of 520,806,528,621 is 220231440.

Find LCM of 520,806,528,621 with Prime Factorization

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

2 x 2 x 2 x 3 x 13 x 5 x 31 x 22 x 207 = 220231440

Therefore, the lowest common multiple of 520,806,528,621 is 220231440.

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 806 x 528 x 621 = 137424418560

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

806 : 1, 2, 13, 26, 31, 62, 403, 806

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,806,528,621, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

806:2x 13x 31

528:2x 2x 2x 2x 3x 11

621:3x 3x 3x 23

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 2x 3x 13 = 624

Therefore, the value for common factors is 624.

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 = 137424418560/(1x624)

LCM = 137424418560/624

LCM = 220231440

Thus, we can understand that the LCM of 520,806,528,621 is 220231440.
