Given numbers are 843,81,561

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

The LCM of 843,81,561 is 4256307.

Find LCM of 843,81,561 with Prime Factorization

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

3 x 281 x 27 x 187 = 4256307

Therefore, the lowest common multiple of 843,81,561 is 4256307.

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.

843 x 81 x 561 = 38306763

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.

843 : 1, 3, 281, 843

81 : 1, 3, 9, 27, 81

561 : 1, 3, 11, 17, 33, 51, 187, 561

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,81,561, is 3.

Now, the common factors can be found like this.

843:3x 281

81:3x 3x 3x 3

561:3x 11x 17

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 = 38306763/(3x3)

LCM = 38306763/9

LCM = 4256307

Thus, we can understand that the LCM of 843,81,561 is 4256307.

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

• LCM of 621, 87, 535
• LCM of 842, 95, 318
