The LCM of 391,811,230,460 is 6342020.

Find LCM of 391,811,230,460 with Prime Factorization


2 391, 811, 230, 460
5 391, 811, 115, 230
23 391, 811, 23, 46
17, 811, 1, 2

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

2 x 5 x 23 x 17 x 811 x 1 x 2 = 6342020

Therefore, the lowest common multiple of 391,811,230,460 is 6342020.

LCM Formula to Find Lowest Common Multiple of 391,811,230,460

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.

391 x 811 x 230 x 460 = 33549285800

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.

391 : 1, 17, 23, 391

811 : 1, 811

230 : 1, 2, 5, 10, 23, 46, 115, 230

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,811,230,460, is 1.

Now, the common factors can be found like this.

391:17x 23

811:811

230:2x 5x 23

460:2x 2x 5x 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 5x 23x 23 = 5290

Therefore, the value for common factors is 5290.

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 = 33549285800/(1x5290)

LCM = 33549285800/5290

LCM = 6342020

Thus, we can understand that the LCM of 391,811,230,460 is 6342020.
