Find LCM of 836,847,756,734,392 with Prime Factorization
| 2 | 836, 847, 756, 734, 392 |
| 2 | 418, 847, 378, 367, 196 |
| 7 | 209, 847, 189, 367, 98 |
| 11 | 209, 121, 27, 367, 14 |
| 19, 11, 27, 367, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 19 x 11 x 27 x 367 x 14 = 8930070072
Therefore, the lowest common multiple of 836,847,756,734,392 is 8930070072.
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.
836 x 847 x 756 x 734 x 392 = 154025848601856
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
847 : 1, 7, 11, 77, 121, 847
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
734 : 1, 2, 367, 734
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,847,756,734,392, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
847:7x 11x 11
756:2x 2x 3x 3x 3x 7
734:2x 367
392:2x 2x 2x 7x 7
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 2x 2x 7x 7x 11 = 17248
Therefore, the value for common factors is 17248.
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 = 154025848601856/(1x17248)
LCM = 154025848601856/17248
LCM = 8930070072
Thus, we can understand that the LCM of 836,847,756,734,392 is 8930070072.
