Calculate the LCM of 308,872,920,439

Given numbers are 308,872,920,439

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

The LCM of 308,872,920,439 is 3389764840.

Find LCM of 308,872,920,439 with Prime Factorization


2 308, 872, 920, 439
2 154, 436, 460, 439
2 77, 218, 230, 439
77, 109, 115, 439

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

2 x 2 x 2 x 77 x 109 x 115 x 439 = 3389764840

Therefore, the lowest common multiple of 308,872,920,439 is 3389764840.

LCM Formula to Find Lowest Common Multiple of 308,872,920,439

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.

308 x 872 x 920 x 439 = 108472474880

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.

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

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

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,872,920,439, is 1.

Now, the common factors can be found like this.

308:2x 2x 7x 11

872:2x 2x 2x 109

920:2x 2x 2x 5x 23

439:439

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 2 = 32

Therefore, the value for common factors is 32.

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 = 108472474880/(1x32)

LCM = 108472474880/32

LCM = 3389764840

Thus, we can understand that the LCM of 308,872,920,439 is 3389764840.
