Given numbers are 191,396,284,728

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

The LCM of 191,396,284,728 is 977368392.

Find LCM of 191,396,284,728 with Prime Factorization

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

2 x 2 x 191 x 99 x 71 x 182 = 977368392

Therefore, the lowest common multiple of 191,396,284,728 is 977368392.

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.

191 x 396 x 284 x 728 = 15637894272

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.

191 : 1, 191

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

284 : 1, 2, 4, 71, 142, 284

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,396,284,728, is 1.

Now, the common factors can be found like this.

191:191

396:2x 2x 3x 3x 11

284:2x 2x 71

728:2x 2x 2x 7x 13

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 2 = 16

Therefore, the value for common factors is 16.

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 = 15637894272/(1x16)

LCM = 15637894272/16

LCM = 977368392

Thus, we can understand that the LCM of 191,396,284,728 is 977368392.
