Given numbers are 211,327,646,990

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

The LCM of 211,327,646,990 is 7354390230.

Find LCM of 211,327,646,990 with Prime Factorization

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

2 x 3 x 211 x 109 x 323 x 165 = 7354390230

Therefore, the lowest common multiple of 211,327,646,990 is 7354390230.

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.

211 x 327 x 646 x 990 = 44126341380

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.

211 : 1, 211

327 : 1, 3, 109, 327

646 : 1, 2, 17, 19, 34, 38, 323, 646

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,327,646,990, is 1.

Now, the common factors can be found like this.

211:211

327:3x 109

646:2x 17x 19

990:2x 3x 3x 5x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 44126341380/(1x6)

LCM = 44126341380/6

LCM = 7354390230

Thus, we can understand that the LCM of 211,327,646,990 is 7354390230.
