Find LCM of 831,847,247,495,715 with Prime Factorization
| 3 | 831, 847, 247, 495, 715 |
| 5 | 277, 847, 247, 165, 715 |
| 11 | 277, 847, 247, 33, 143 |
| 13 | 277, 77, 247, 3, 13 |
| 277, 77, 19, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 277 x 77 x 19 x 3 x 1 = 2607790185
Therefore, the lowest common multiple of 831,847,247,495,715 is 2607790185.
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.
831 x 847 x 247 x 495 x 715 = 61530809415075
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.
831 : 1, 3, 277, 831
847 : 1, 7, 11, 77, 121, 847
247 : 1, 13, 19, 247
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,847,247,495,715, is 1.
Now, the common factors can be found like this.
831:3x 277
847:7x 11x 11
247:13x 19
495:3x 3x 5x 11
715:5x 11x 13
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 11x 13 = 23595
Therefore, the value for common factors is 23595.
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 = 61530809415075/(1x23595)
LCM = 61530809415075/23595
LCM = 2607790185
Thus, we can understand that the LCM of 831,847,247,495,715 is 2607790185.
