Given numbers are 669,3993

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

The LCM of 669,3993 is 890439.

Find LCM of 669,3993 with Prime Factorization

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

3 x 223 x 1331 = 890439

Therefore, the lowest common multiple of 669,3993 is 890439.

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.

669 x 3993 = 2671317

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.

669 : 1, 3, 223, 669

3993 : 1, 3, 11, 33, 121, 363, 1331, 3993

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,3993, is 3.

Now, the common factors can be found like this.

669:3x 223

3993:3x 11x 11x 11

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

= 1

Therefore, the value for common factors is 1.

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 = 2671317/(3x1)

LCM = 2671317/3

LCM = 890439

Thus, we can understand that the LCM of 669,3993 is 890439.
