Given numbers are 257,451,411,198

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

The LCM of 257,451,411,198 is 285826662.

Find LCM of 257,451,411,198 with Prime Factorization

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

3 x 11 x 257 x 41 x 137 x 6 = 285826662

Therefore, the lowest common multiple of 257,451,411,198 is 285826662.

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.

257 x 451 x 411 x 198 = 9432279846

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.

257 : 1, 257

451 : 1, 11, 41, 451

411 : 1, 3, 137, 411

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,451,411,198, is 1.

Now, the common factors can be found like this.

257:257

451:11x 41

411:3x 137

198:2x 3x 3x 11

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

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 9432279846/(1x33)

LCM = 9432279846/33

LCM = 285826662

Thus, we can understand that the LCM of 257,451,411,198 is 285826662.
