Given numbers are 645,633,336

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

The LCM of 645,633,336 is 15242640.

Find LCM of 645,633,336 with Prime Factorization

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

3 x 215 x 211 x 112 = 15242640

Therefore, the lowest common multiple of 645,633,336 is 15242640.

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.

645 x 633 x 336 = 137183760

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

633 : 1, 3, 211, 633

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,633,336, is 3.

Now, the common factors can be found like this.

645:3x 5x 43

633:3x 211

336:2x 2x 2x 2x 3x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 137183760/(3x3)

LCM = 137183760/9

LCM = 15242640

Thus, we can understand that the LCM of 645,633,336 is 15242640.

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

• LCM of 660, 150, 670
