Given numbers are 193,121,325,221

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

The LCM of 193,121,325,221 is 129025325.

Find LCM of 193,121,325,221 with Prime Factorization

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

13 x 193 x 121 x 25 x 17 = 129025325

Therefore, the lowest common multiple of 193,121,325,221 is 129025325.

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.

193 x 121 x 325 x 221 = 1677329225

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.

193 : 1, 193

121 : 1, 11, 121

325 : 1, 5, 13, 25, 65, 325

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,121,325,221, is 1.

Now, the common factors can be found like this.

193:193

121:11x 11

325:5x 5x 13

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 1677329225/(1x13)

LCM = 1677329225/13

LCM = 129025325

Thus, we can understand that the LCM of 193,121,325,221 is 129025325.
