Given numbers are 816,511,994,905

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

The LCM of 816,511,994,905 is 26792792880.

Find LCM of 816,511,994,905 with Prime Factorization

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

2 x 7 x 408 x 73 x 71 x 905 = 26792792880

Therefore, the lowest common multiple of 816,511,994,905 is 26792792880.

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 511 x 994 x 905 = 375099100320

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

511 : 1, 7, 73, 511

994 : 1, 2, 7, 14, 71, 142, 497, 994

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,511,994,905, is 1.

Now, the common factors can be found like this.

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

511:7x 73

994:2x 7x 71

905:5x 181

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 375099100320/(1x14)

LCM = 375099100320/14

LCM = 26792792880

Thus, we can understand that the LCM of 816,511,994,905 is 26792792880.
