Given numbers are 1503,1689

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

The LCM of 1503,1689 is 846189.

Find LCM of 1503,1689 with Prime Factorization

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

3 x 501 x 563 = 846189

Therefore, the lowest common multiple of 1503,1689 is 846189.

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.

1503 x 1689 = 2538567

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.

1503 : 1, 3, 9, 167, 501, 1503

1689 : 1, 3, 563, 1689

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1503,1689, is 3.

Now, the common factors can be found like this.

1503:3x 3x 167

1689:3x 563

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 = 2538567/(3x1)

LCM = 2538567/3

LCM = 846189

Thus, we can understand that the LCM of 1503,1689 is 846189.
