Given numbers are 816,487,720,162

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

The LCM of 816,487,720,162 is 53647920.

Find LCM of 816,487,720,162 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 3 x 17 x 487 x 5 x 9 = 53647920

Therefore, the lowest common multiple of 816,487,720,162 is 53647920.

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 487 x 720 x 162 = 46351802880

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

487 : 1, 487

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,487,720,162, is 1.

Now, the common factors can be found like this.

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

487:487

720:2x 2x 2x 2x 3x 3x 5

162:2x 3x 3x 3x 3

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 3x 3x 3 = 864

Therefore, the value for common factors is 864.

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 = 46351802880/(1x864)

LCM = 46351802880/864

LCM = 53647920

Thus, we can understand that the LCM of 816,487,720,162 is 53647920.
