Calculate the LCM of 817,646,443,493

Given numbers are 817,646,443,493

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

The LCM of 817,646,443,493 is 356863966.

Find LCM of 817,646,443,493 with Prime Factorization


17 817, 646, 443, 493
19 817, 38, 443, 29
43, 2, 443, 29

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

17 x 19 x 43 x 2 x 443 x 29 = 356863966

Therefore, the lowest common multiple of 817,646,443,493 is 356863966.

LCM Formula to Find Lowest Common Multiple of 817,646,443,493

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.

817 x 646 x 443 x 493 = 115267061018

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.

817 : 1, 19, 43, 817

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

443 : 1, 443

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,646,443,493, is 1.

Now, the common factors can be found like this.

817:19x 43

646:2x 17x 19

443:443

493:17x 29

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

17x 19 = 323

Therefore, the value for common factors is 323.

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 = 115267061018/(1x323)

LCM = 115267061018/323

LCM = 356863966

Thus, we can understand that the LCM of 817,646,443,493 is 356863966.
