Given numbers are 1605,3685

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

The LCM of 1605,3685 is 1182885.

Find LCM of 1605,3685 with Prime Factorization

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

5 x 321 x 737 = 1182885

Therefore, the lowest common multiple of 1605,3685 is 1182885.

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.

1605 x 3685 = 5914425

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.

1605 : 1, 3, 5, 15, 107, 321, 535, 1605

3685 : 1, 5, 11, 55, 67, 335, 737, 3685

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1605,3685, is 5.

Now, the common factors can be found like this.

1605:3x 5x 107

3685:5x 11x 67

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 = 5914425/(5x1)

LCM = 5914425/5

LCM = 1182885

Thus, we can understand that the LCM of 1605,3685 is 1182885.
