Given numbers are 397,157,663,397

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

The LCM of 397,157,663,397 is 41324127.

Find LCM of 397,157,663,397 with Prime Factorization

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

397 x 1 x 157 x 663 x 1 = 41324127

Therefore, the lowest common multiple of 397,157,663,397 is 41324127.

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.

397 x 157 x 663 x 397 = 16405678419

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.

397 : 1, 397

157 : 1, 157

663 : 1, 3, 13, 17, 39, 51, 221, 663

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,157,663,397, is 1.

Now, the common factors can be found like this.

397:397

157:157

663:3x 13x 17

397:397

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

397 = 397

Therefore, the value for common factors is 397.

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 = 16405678419/(1x397)

LCM = 16405678419/397

LCM = 41324127

Thus, we can understand that the LCM of 397,157,663,397 is 41324127.
