Find LCM of 847,158,796,836,455 with Prime Factorization
| 2 | 847, 158, 796, 836, 455 |
| 2 | 847, 79, 398, 418, 455 |
| 7 | 847, 79, 199, 209, 455 |
| 11 | 121, 79, 199, 209, 65 |
| 11, 79, 199, 19, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 11 x 79 x 199 x 19 x 65 = 65779493780
Therefore, the lowest common multiple of 847,158,796,836,455 is 65779493780.
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.
847 x 158 x 796 x 836 x 455 = 40520168168480
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.
847 : 1, 7, 11, 77, 121, 847
158 : 1, 2, 79, 158
796 : 1, 2, 4, 199, 398, 796
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,158,796,836,455, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
158:2x 79
796:2x 2x 199
836:2x 2x 11x 19
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7x 11 = 616
Therefore, the value for common factors is 616.
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 = 40520168168480/(1x616)
LCM = 40520168168480/616
LCM = 65779493780
Thus, we can understand that the LCM of 847,158,796,836,455 is 65779493780.
