Given numbers are 81,93,93,96,422

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

The LCM of 81,93,93,96,422 is 16954272.

Find LCM of 81,93,93,96,422 with Prime Factorization

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

2 x 3 x 31 x 27 x 1 x 1 x 16 x 211 = 16954272

Therefore, the lowest common multiple of 81,93,93,96,422 is 16954272.

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.

81 x 93 x 93 x 96 x 422 = 28381451328

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.

81 : 1, 3, 9, 27, 81

93 : 1, 3, 31, 93

93 : 1, 3, 31, 93

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

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 81,93,93,96,422, is 1.

Now, the common factors can be found like this.

81:3x 3x 3x 3

93:3x 31

93:3x 31

96:2x 2x 2x 2x 2x 3

422:2x 211

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 3x 31 = 1674

Therefore, the value for common factors is 1674.

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 = 28381451328/(1x1674)

LCM = 28381451328/1674

LCM = 16954272

Thus, we can understand that the LCM of 81,93,93,96,422 is 16954272.
