Calculate the LCM of 997,315,363,605

Given numbers are 997,315,363,605

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

The LCM of 997,315,363,605 is 38000655.

Find LCM of 997,315,363,605 with Prime Factorization


3 997, 315, 363, 605
5 997, 105, 121, 605
11 997, 21, 121, 121
11 997, 21, 11, 11
997, 21, 1, 1

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

3 x 5 x 11 x 11 x 997 x 21 x 1 x 1 = 38000655

Therefore, the lowest common multiple of 997,315,363,605 is 38000655.

LCM Formula to Find Lowest Common Multiple of 997,315,363,605

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 315 x 363 x 605 = 68971188825

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

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

363 : 1, 3, 11, 33, 121, 363

605 : 1, 5, 11, 55, 121, 605

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,315,363,605, is 1.

Now, the common factors can be found like this.

997:997

315:3x 3x 5x 7

363:3x 11x 11

605:5x 11x 11

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

3x 5x 11x 11 = 1815

Therefore, the value for common factors is 1815.

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 = 68971188825/(1x1815)

LCM = 68971188825/1815

LCM = 38000655

Thus, we can understand that the LCM of 997,315,363,605 is 38000655.
