Given numbers are 816,411,643

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

The LCM of 816,411,643 is 71882256.

Find LCM of 816,411,643 with Prime Factorization

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

3 x 272 x 137 x 643 = 71882256

Therefore, the lowest common multiple of 816,411,643 is 71882256.

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.

816 x 411 x 643 = 215646768

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

411 : 1, 3, 137, 411

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,411,643, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

411:3x 137

643:643

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

3 = 3

Therefore, the value for common factors is 3.

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 = 215646768/(1x3)

LCM = 215646768/3

LCM = 71882256

Thus, we can understand that the LCM of 816,411,643 is 71882256.
