Given numbers are 561,85,122

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

The LCM of 561,85,122 is 342210.

Find LCM of 561,85,122 with Prime Factorization

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

17 x 33 x 5 x 122 = 342210

Therefore, the lowest common multiple of 561,85,122 is 342210.

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.

561 x 85 x 122 = 5817570

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.

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

85 : 1, 5, 17, 85

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,85,122, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

85:5x 17

122:2x 61

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

17 = 17

Therefore, the value for common factors is 17.

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 = 5817570/(1x17)

LCM = 5817570/17

LCM = 342210

Thus, we can understand that the LCM of 561,85,122 is 342210.

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

• LCM of 674, 90, 330
• LCM of 287, 23, 734
