Given numbers are 431,55,187

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

The LCM of 431,55,187 is 402985.

Find LCM of 431,55,187 with Prime Factorization

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

11 x 431 x 5 x 17 = 402985

Therefore, the lowest common multiple of 431,55,187 is 402985.

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.

431 x 55 x 187 = 4432835

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.

431 : 1, 431

55 : 1, 5, 11, 55

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,55,187, is 1.

Now, the common factors can be found like this.

431:431

55:5x 11

187:11x 17

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 = 4432835/(1x11)

LCM = 4432835/11

LCM = 402985

Thus, we can understand that the LCM of 431,55,187 is 402985.

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

• LCM of 105, 82, 483
• LCM of 600, 81, 816
