Given numbers are 911,21,135

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

The LCM of 911,21,135 is 860895.

Find LCM of 911,21,135 with Prime Factorization

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

3 x 911 x 7 x 45 = 860895

Therefore, the lowest common multiple of 911,21,135 is 860895.

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.

911 x 21 x 135 = 2582685

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.

911 : 1, 911

21 : 1, 3, 7, 21

135 : 1, 3, 5, 9, 15, 27, 45, 135

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,21,135, is 1.

Now, the common factors can be found like this.

911:911

21:3x 7

135:3x 3x 3x 5

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 = 2582685/(1x3)

LCM = 2582685/3

LCM = 860895

Thus, we can understand that the LCM of 911,21,135 is 860895.

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

• LCM of 225, 37, 539
• LCM of 315, 87, 883
• LCM of 651, 34, 709
