Given numbers are 213,193,193,457

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

The LCM of 213,193,193,457 is 18786813.

Find LCM of 213,193,193,457 with Prime Factorization

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

193 x 213 x 1 x 1 x 457 = 18786813

Therefore, the lowest common multiple of 213,193,193,457 is 18786813.

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.

213 x 193 x 193 x 457 = 3625854909

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.

213 : 1, 3, 71, 213

193 : 1, 193

193 : 1, 193

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,193,193,457, is 1.

Now, the common factors can be found like this.

213:3x 71

193:193

193:193

457:457

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

193 = 193

Therefore, the value for common factors is 193.

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 = 3625854909/(1x193)

LCM = 3625854909/193

LCM = 18786813

Thus, we can understand that the LCM of 213,193,193,457 is 18786813.

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

• LCM of 137, 179, 232, 557
