Given numbers are 997,198,997,457

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

The LCM of 997,198,997,457 is 90214542.

Find LCM of 997,198,997,457 with Prime Factorization

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

997 x 1 x 198 x 1 x 457 = 90214542

Therefore, the lowest common multiple of 997,198,997,457 is 90214542.

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.

997 x 198 x 997 x 457 = 89943898374

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.

997 : 1, 997

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

997 : 1, 997

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,198,997,457, is 1.

Now, the common factors can be found like this.

997:997

198:2x 3x 3x 11

997:997

457:457

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

997 = 997

Therefore, the value for common factors is 997.

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 = 89943898374/(1x997)

LCM = 89943898374/997

LCM = 90214542

Thus, we can understand that the LCM of 997,198,997,457 is 90214542.
