Given numbers are 816,165,965,918

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

The LCM of 816,165,965,918 is 77956560.

Find LCM of 816,165,965,918 with Prime Factorization

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

2 x 3 x 5 x 17 x 8 x 11 x 193 x 9 = 77956560

Therefore, the lowest common multiple of 816,165,965,918 is 77956560.

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 165 x 965 x 918 = 119273536800

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

165 : 1, 3, 5, 11, 15, 33, 55, 165

965 : 1, 5, 193, 965

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,165,965,918, is 1.

Now, the common factors can be found like this.

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

165:3x 5x 11

965:5x 193

918:2x 3x 3x 3x 17

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

2x 3x 3x 5x 17 = 1530

Therefore, the value for common factors is 1530.

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 = 119273536800/(1x1530)

LCM = 119273536800/1530

LCM = 77956560

Thus, we can understand that the LCM of 816,165,965,918 is 77956560.
