The LCM of 538,715,847,605 is 29619590.

Find LCM of 538,715,847,605 with Prime Factorization


5 538, 715, 847, 605
11 538, 143, 847, 121
11 538, 13, 77, 11
538, 13, 7, 1

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

5 x 11 x 11 x 538 x 13 x 7 x 1 = 29619590

Therefore, the lowest common multiple of 538,715,847,605 is 29619590.

LCM Formula to Find Lowest Common Multiple of 538,715,847,605

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.

538 x 715 x 847 x 605 = 197118371450

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.

538 : 1, 2, 269, 538

715 : 1, 5, 11, 13, 55, 65, 143, 715

847 : 1, 7, 11, 77, 121, 847

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 538,715,847,605, is 1.

Now, the common factors can be found like this.

538:2x 269

715:5x 11x 13

847:7x 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.

5x 11x 11x 11 = 6655

Therefore, the value for common factors is 6655.

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 = 197118371450/(1x6655)

LCM = 197118371450/6655

LCM = 29619590

Thus, we can understand that the LCM of 538,715,847,605 is 29619590.
