The LCM of 813,720,799,325,542 is 10133557200.
Find LCM of 813,720,799,325,542 with Prime Factorization
| 2 | 813, 720, 799, 325, 542 |
| 3 | 813, 360, 799, 325, 271 |
| 5 | 271, 120, 799, 325, 271 |
| 271 | 271, 24, 799, 65, 271 |
| 1, 24, 799, 65, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 271 x 1 x 24 x 799 x 65 x 1 = 10133557200
Therefore, the lowest common multiple of 813,720,799,325,542 is 10133557200.
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.
813 x 720 x 799 x 325 x 542 = 82385820036000
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.
813 : 1, 3, 271, 813
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
799 : 1, 17, 47, 799
325 : 1, 5, 13, 25, 65, 325
542 : 1, 2, 271, 542
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,720,799,325,542, is 1.
Now, the common factors can be found like this.
813:3x 271
720:2x 2x 2x 2x 3x 3x 5
799:17x 47
325:5x 5x 13
542:2x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 271 = 8130
Therefore, the value for common factors is 8130.
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 = 82385820036000/(1x8130)
LCM = 82385820036000/8130
LCM = 10133557200
Thus, we can understand that the LCM of 813,720,799,325,542 is 10133557200.
