Find LCM of 719,686,456,836,847 with Prime Factorization
| 2 | 719, 686, 456, 836, 847 |
| 2 | 719, 343, 228, 418, 847 |
| 7 | 719, 343, 114, 209, 847 |
| 11 | 719, 49, 114, 209, 121 |
| 19 | 719, 49, 114, 19, 11 |
| 719, 49, 6, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 19 x 719 x 49 x 6 x 1 x 11 = 13607339592
Therefore, the lowest common multiple of 719,686,456,836,847 is 13607339592.
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.
719 x 686 x 456 x 836 x 847 = 159260302584768
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.
719 : 1, 719
686 : 1, 2, 7, 14, 49, 98, 343, 686
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,686,456,836,847, is 1.
Now, the common factors can be found like this.
719:719
686:2x 7x 7x 7
456:2x 2x 2x 3x 19
836:2x 2x 11x 19
847:7x 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.
2x 2x 2x 7x 11x 19 = 11704
Therefore, the value for common factors is 11704.
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 = 159260302584768/(1x11704)
LCM = 159260302584768/11704
LCM = 13607339592
Thus, we can understand that the LCM of 719,686,456,836,847 is 13607339592.
