Given numbers are 816,731,646,622,880

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

The LCM of 816,731,646,622,880 is 11403424560.

Find LCM of 816,731,646,622,880 with Prime Factorization

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

2 x 2 x 2 x 2 x 17 x 3 x 43 x 19 x 311 x 55 = 11403424560

Therefore, the lowest common multiple of 816,731,646,622,880 is 11403424560.

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 731 x 646 x 622 x 880 = 210917740661760

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

731 : 1, 17, 43, 731

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

622 : 1, 2, 311, 622

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,731,646,622,880, is 1.

Now, the common factors can be found like this.

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

731:17x 43

646:2x 17x 19

622:2x 311

880:2x 2x 2x 2x 5x 11

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 2x 2x 2x 2x 17x 17 = 18496

Therefore, the value for common factors is 18496.

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 = 210917740661760/(1x18496)

LCM = 210917740661760/18496

LCM = 11403424560

Thus, we can understand that the LCM of 816,731,646,622,880 is 11403424560.
