Given numbers are 657,157,394,197

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

The LCM of 657,157,394,197 is 40640706.

Find LCM of 657,157,394,197 with Prime Factorization

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

197 x 657 x 157 x 2 x 1 = 40640706

Therefore, the lowest common multiple of 657,157,394,197 is 40640706.

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.

657 x 157 x 394 x 197 = 8006219082

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.

657 : 1, 3, 9, 73, 219, 657

157 : 1, 157

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 657,157,394,197, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

157:157

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 = 8006219082/(1x197)

LCM = 8006219082/197

LCM = 40640706

Thus, we can understand that the LCM of 657,157,394,197 is 40640706.
