Given numbers are 188,154,191,257

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

The LCM of 188,154,191,257 is 710583412.

Find LCM of 188,154,191,257 with Prime Factorization

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

2 x 94 x 77 x 191 x 257 = 710583412

Therefore, the lowest common multiple of 188,154,191,257 is 710583412.

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.

188 x 154 x 191 x 257 = 1421166824

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.

188 : 1, 2, 4, 47, 94, 188

154 : 1, 2, 7, 11, 14, 22, 77, 154

191 : 1, 191

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,154,191,257, is 1.

Now, the common factors can be found like this.

188:2x 2x 47

154:2x 7x 11

191:191

257:257

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

2 = 2

Therefore, the value for common factors is 2.

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 = 1421166824/(1x2)

LCM = 1421166824/2

LCM = 710583412

Thus, we can understand that the LCM of 188,154,191,257 is 710583412.

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