Given numbers are 1636,1644

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

The LCM of 1636,1644 is 672396.

Find LCM of 1636,1644 with Prime Factorization

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

2 x 2 x 409 x 411 = 672396

Therefore, the lowest common multiple of 1636,1644 is 672396.

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.

1636 x 1644 = 2689584

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.

1636 : 1, 2, 4, 409, 818, 1636

1644 : 1, 2, 3, 4, 6, 12, 137, 274, 411, 548, 822, 1644

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1636,1644, is 4.

Now, the common factors can be found like this.

1636:2x 2x 409

1644:2x 2x 3x 137

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 = 2689584/(4x1)

LCM = 2689584/4

LCM = 672396

Thus, we can understand that the LCM of 1636,1644 is 672396.

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

• LCM of 4776, 2302
