Given numbers are 997,781,442,481

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

The LCM of 997,781,442,481 is 12734156578.

Find LCM of 997,781,442,481 with Prime Factorization

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

13 x 997 x 781 x 34 x 37 = 12734156578

Therefore, the lowest common multiple of 997,781,442,481 is 12734156578.

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 781 x 442 x 481 = 165544035514

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

781 : 1, 11, 71, 781

442 : 1, 2, 13, 17, 26, 34, 221, 442

481 : 1, 13, 37, 481

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,781,442,481, is 1.

Now, the common factors can be found like this.

997:997

781:11x 71

442:2x 13x 17

481:13x 37

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

13 = 13

Therefore, the value for common factors is 13.

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 = 165544035514/(1x13)

LCM = 165544035514/13

LCM = 12734156578

Thus, we can understand that the LCM of 997,781,442,481 is 12734156578.
