Given numbers are 816,908,207,920

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

The LCM of 816,908,207,920 is 63905040.

Find LCM of 816,908,207,920 with Prime Factorization

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

2 x 2 x 2 x 3 x 23 x 34 x 227 x 3 x 5 = 63905040

Therefore, the lowest common multiple of 816,908,207,920 is 63905040.

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 908 x 207 x 920 = 141102328320

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

908 : 1, 2, 4, 227, 454, 908

207 : 1, 3, 9, 23, 69, 207

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,908,207,920, is 1.

Now, the common factors can be found like this.

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

908:2x 2x 227

207:3x 3x 23

920:2x 2x 2x 5x 23

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 23 = 2208

Therefore, the value for common factors is 2208.

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 = 141102328320/(1x2208)

LCM = 141102328320/2208

LCM = 63905040

Thus, we can understand that the LCM of 816,908,207,920 is 63905040.
