Given numbers are 816,813,990,695

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

The LCM of 816,813,990,695 is 5071754160.

Find LCM of 816,813,990,695 with Prime Factorization

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

2 x 3 x 5 x 136 x 271 x 33 x 139 = 5071754160

Therefore, the lowest common multiple of 816,813,990,695 is 5071754160.

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 813 x 990 x 695 = 456457874400

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

813 : 1, 3, 271, 813

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

695 : 1, 5, 139, 695

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,813,990,695, is 1.

Now, the common factors can be found like this.

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

813:3x 271

990:2x 3x 3x 5x 11

695:5x 139

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 5 = 90

Therefore, the value for common factors is 90.

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 = 456457874400/(1x90)

LCM = 456457874400/90

LCM = 5071754160

Thus, we can understand that the LCM of 816,813,990,695 is 5071754160.
