Given numbers are 520,507,637,809

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

The LCM of 520,507,637,809 is 803919480.

Find LCM of 520,507,637,809 with Prime Factorization

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

13 x 40 x 39 x 49 x 809 = 803919480

Therefore, the lowest common multiple of 520,507,637,809 is 803919480.

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 507 x 637 x 809 = 135862392120

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

507 : 1, 3, 13, 39, 169, 507

637 : 1, 7, 13, 49, 91, 637

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,507,637,809, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

507:3x 13x 13

637:7x 7x 13

809:809

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 135862392120/(1x169)

LCM = 135862392120/169

LCM = 803919480

Thus, we can understand that the LCM of 520,507,637,809 is 803919480.
