Given numbers are 181,470,193,195

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

The LCM of 181,470,193,195 is 640321890.

Find LCM of 181,470,193,195 with Prime Factorization

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

5 x 181 x 94 x 193 x 39 = 640321890

Therefore, the lowest common multiple of 181,470,193,195 is 640321890.

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.

181 x 470 x 193 x 195 = 3201609450

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.

181 : 1, 181

470 : 1, 2, 5, 10, 47, 94, 235, 470

193 : 1, 193

195 : 1, 3, 5, 13, 15, 39, 65, 195

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,470,193,195, is 1.

Now, the common factors can be found like this.

181:181

470:2x 5x 47

193:193

195:3x 5x 13

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

5 = 5

Therefore, the value for common factors is 5.

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 = 3201609450/(1x5)

LCM = 3201609450/5

LCM = 640321890

Thus, we can understand that the LCM of 181,470,193,195 is 640321890.

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