Calculate the LCM of 399,426,646,162

Given numbers are 399,426,646,162

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

The LCM of 399,426,646,162 is 26006022.

Find LCM of 399,426,646,162 with Prime Factorization


2 399, 426, 646, 162
3 399, 213, 323, 81
19 133, 71, 323, 27
7, 71, 17, 27

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

2 x 3 x 19 x 7 x 71 x 17 x 27 = 26006022

Therefore, the lowest common multiple of 399,426,646,162 is 26006022.

LCM Formula to Find Lowest Common Multiple of 399,426,646,162

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.

399 x 426 x 646 x 162 = 17788119048

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,426,646,162, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

426:2x 3x 71

646:2x 17x 19

162:2x 3x 3x 3x 3

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 3x 19 = 684

Therefore, the value for common factors is 684.

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 = 17788119048/(1x684)

LCM = 17788119048/684

LCM = 26006022

Thus, we can understand that the LCM of 399,426,646,162 is 26006022.
