Given numbers are 3645,1389

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

The LCM of 3645,1389 is 1687635.

Find LCM of 3645,1389 with Prime Factorization

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

3 x 1215 x 463 = 1687635

Therefore, the lowest common multiple of 3645,1389 is 1687635.

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.

3645 x 1389 = 5062905

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.

3645 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 243, 405, 729, 1215, 3645

1389 : 1, 3, 463, 1389

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3645,1389, is 3.

Now, the common factors can be found like this.

3645:3x 3x 3x 3x 3x 3x 5

1389:3x 463

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 = 5062905/(3x1)

LCM = 5062905/3

LCM = 1687635

Thus, we can understand that the LCM of 3645,1389 is 1687635.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 5691, 2517
• LCM of 5299, 8848
