Given numbers are 1605,2661

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

The LCM of 1605,2661 is 1423635.

Find LCM of 1605,2661 with Prime Factorization

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

3 x 535 x 887 = 1423635

Therefore, the lowest common multiple of 1605,2661 is 1423635.

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 2661 = 4270905

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

2661 : 1, 3, 887, 2661

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1605,2661, is 3.

Now, the common factors can be found like this.

1605:3x 5x 107

2661:3x 887

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 = 4270905/(3x1)

LCM = 4270905/3

LCM = 1423635

Thus, we can understand that the LCM of 1605,2661 is 1423635.
