Calculate the LCM of 819,426,862,862

Given numbers are 819,426,862,862

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

The LCM of 819,426,862,862 is 50124438.

Find LCM of 819,426,862,862 with Prime Factorization


2 819, 426, 862, 862
3 819, 213, 431, 431
431 273, 71, 431, 431
273, 71, 1, 1

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

2 x 3 x 431 x 273 x 71 x 1 x 1 = 50124438

Therefore, the lowest common multiple of 819,426,862,862 is 50124438.

LCM Formula to Find Lowest Common Multiple of 819,426,862,862

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.

819 x 426 x 862 x 862 = 259243593336

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.

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

426 : 1, 2, 3, 6, 71, 142, 213, 426

862 : 1, 2, 431, 862

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,426,862,862, is 1.

Now, the common factors can be found like this.

819:3x 3x 7x 13

426:2x 3x 71

862:2x 431

862:2x 431

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 3x 431 = 5172

Therefore, the value for common factors is 5172.

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 = 259243593336/(1x5172)

LCM = 259243593336/5172

LCM = 50124438

Thus, we can understand that the LCM of 819,426,862,862 is 50124438.
