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

2 x 2 x 2 x 3 x 3 x 8 x 9 x 197 x 19 = 19403712

Therefore, the lowest common multiple of 192,648,788,171 is 19403712.

LCM Formula to Find Lowest Common Multiple of 192,648,788,171

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.

192 x 648 x 788 x 171 = 16764807168

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.

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

788 : 1, 2, 4, 197, 394, 788

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,648,788,171, is 1.

Now, the common factors can be found like this.

192:2x 2x 2x 2x 2x 2x 3

648:2x 2x 2x 3x 3x 3x 3

788:2x 2x 197

171:3x 3x 19

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 = 16764807168/(1x864)

LCM = 16764807168/864

LCM = 19403712

Thus, we can understand that the LCM of 192,648,788,171 is 19403712.
