Given numbers are 393,781,394,197

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

The LCM of 393,781,394,197 is 120931602.

Find LCM of 393,781,394,197 with Prime Factorization

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

197 x 393 x 781 x 2 x 1 = 120931602

Therefore, the lowest common multiple of 393,781,394,197 is 120931602.

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.

393 x 781 x 394 x 197 = 23823525594

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.

393 : 1, 3, 131, 393

781 : 1, 11, 71, 781

394 : 1, 2, 197, 394

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,781,394,197, is 1.

Now, the common factors can be found like this.

393:3x 131

781:11x 71

394:2x 197

197:197

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

197 = 197

Therefore, the value for common factors is 197.

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 = 23823525594/(1x197)

LCM = 23823525594/197

LCM = 120931602

Thus, we can understand that the LCM of 393,781,394,197 is 120931602.
