Given numbers are 212,206,212,990

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

The LCM of 212,206,212,990 is 10808820.

Find LCM of 212,206,212,990 with Prime Factorization

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

2 x 2 x 53 x 1 x 103 x 1 x 495 = 10808820

Therefore, the lowest common multiple of 212,206,212,990 is 10808820.

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.

212 x 206 x 212 x 990 = 9165879360

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.

212 : 1, 2, 4, 53, 106, 212

206 : 1, 2, 103, 206

212 : 1, 2, 4, 53, 106, 212

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,206,212,990, is 2.

Now, the common factors can be found like this.

212:2x 2x 53

206:2x 103

212:2x 2x 53

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 2x 2x 53 = 424

Therefore, the value for common factors is 424.

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 = 9165879360/(2x424)

LCM = 9165879360/848

LCM = 10808820

Thus, we can understand that the LCM of 212,206,212,990 is 10808820.
