Calculate the LCM of 509,813,872,860

Given numbers are 509,813,872,860

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

The LCM of 509,813,872,860 is 77582411160.

Find LCM of 509,813,872,860 with Prime Factorization


2 509, 813, 872, 860
2 509, 813, 436, 430
509, 813, 218, 215

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

2 x 2 x 509 x 813 x 218 x 215 = 77582411160

Therefore, the lowest common multiple of 509,813,872,860 is 77582411160.

LCM Formula to Find Lowest Common Multiple of 509,813,872,860

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.

509 x 813 x 872 x 860 = 310329644640

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.

509 : 1, 509

813 : 1, 3, 271, 813

872 : 1, 2, 4, 8, 109, 218, 436, 872

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,813,872,860, is 1.

Now, the common factors can be found like this.

509:509

813:3x 271

872:2x 2x 2x 109

860:2x 2x 5x 43

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 = 310329644640/(1x4)

LCM = 310329644640/4

LCM = 77582411160

Thus, we can understand that the LCM of 509,813,872,860 is 77582411160.
