Given numbers are 885,15,646

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

The LCM of 885,15,646 is 571710.

Find LCM of 885,15,646 with Prime Factorization

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

3 x 5 x 59 x 1 x 646 = 571710

Therefore, the lowest common multiple of 885,15,646 is 571710.

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.

885 x 15 x 646 = 8575650

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.

885 : 1, 3, 5, 15, 59, 177, 295, 885

15 : 1, 3, 5, 15

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,15,646, is 1.

Now, the common factors can be found like this.

885:3x 5x 59

15:3x 5

646:2x 17x 19

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 8575650/(1x15)

LCM = 8575650/15

LCM = 571710

Thus, we can understand that the LCM of 885,15,646 is 571710.

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

• LCM of 105, 96, 696
• LCM of 644, 90, 616
