Given numbers are 1689,6543

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

The LCM of 1689,6543 is 3683709.

Find LCM of 1689,6543 with Prime Factorization

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

3 x 563 x 2181 = 3683709

Therefore, the lowest common multiple of 1689,6543 is 3683709.

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.

1689 x 6543 = 11051127

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.

1689 : 1, 3, 563, 1689

6543 : 1, 3, 9, 727, 2181, 6543

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1689,6543, is 3.

Now, the common factors can be found like this.

1689:3x 563

6543:3x 3x 727

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 = 11051127/(3x1)

LCM = 11051127/3

LCM = 3683709

Thus, we can understand that the LCM of 1689,6543 is 3683709.
