Given numbers are 197,424,394,257,531

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

The LCM of 197,424,394,257,531 is 11398815576.

Find LCM of 197,424,394,257,531 with Prime Factorization

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

2 x 197 x 1 x 212 x 1 x 257 x 531 = 11398815576

Therefore, the lowest common multiple of 197,424,394,257,531 is 11398815576.

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.

197 x 424 x 394 x 257 x 531 = 4491133336944

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.

197 : 1, 197

424 : 1, 2, 4, 8, 53, 106, 212, 424

394 : 1, 2, 197, 394

257 : 1, 257

531 : 1, 3, 9, 59, 177, 531

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,424,394,257,531, is 1.

Now, the common factors can be found like this.

197:197

424:2x 2x 2x 53

394:2x 197

257:257

531:3x 3x 59

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

2x 197 = 394

Therefore, the value for common factors is 394.

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 = 4491133336944/(1x394)

LCM = 4491133336944/394

LCM = 11398815576

Thus, we can understand that the LCM of 197,424,394,257,531 is 11398815576.
