Given numbers are 509,617,389,389

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

The LCM of 509,617,389,389 is 122166617.

Find LCM of 509,617,389,389 with Prime Factorization

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

389 x 509 x 617 x 1 x 1 = 122166617

Therefore, the lowest common multiple of 509,617,389,389 is 122166617.

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 617 x 389 x 389 = 47522814013

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

617 : 1, 617

389 : 1, 389

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,617,389,389, is 1.

Now, the common factors can be found like this.

509:509

617:617

389:389

389:389

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

389 = 389

Therefore, the value for common factors is 389.

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 = 47522814013/(1x389)

LCM = 47522814013/389

LCM = 122166617

Thus, we can understand that the LCM of 509,617,389,389 is 122166617.

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

• LCM of 723, 633, 315, 900
