Given numbers are 173,198,121

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

The LCM of 173,198,121 is 376794.

Find LCM of 173,198,121 with Prime Factorization

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

11 x 173 x 18 x 11 = 376794

Therefore, the lowest common multiple of 173,198,121 is 376794.

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.

173 x 198 x 121 = 4144734

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.

173 : 1, 173

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,198,121, is 1.

Now, the common factors can be found like this.

173:173

198:2x 3x 3x 11

121:11x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 4144734/(1x11)

LCM = 4144734/11

LCM = 376794

Thus, we can understand that the LCM of 173,198,121 is 376794.

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

• LCM of 168, 739, 225
• LCM of 912, 127, 373
