The LCM of 836,505,969,120 is 43062360.
Find LCM of 836,505,969,120 with Prime Factorization
| 2 | 836, 505, 969, 120 |
| 2 | 418, 505, 969, 60 |
| 3 | 209, 505, 969, 30 |
| 5 | 209, 505, 323, 10 |
| 19 | 209, 101, 323, 2 |
| 11, 101, 17, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 11 x 101 x 17 x 2 = 43062360
Therefore, the lowest common multiple of 836,505,969,120 is 43062360.
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 505 x 969 x 120 = 49091090400
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
505 : 1, 5, 101, 505
969 : 1, 3, 17, 19, 51, 57, 323, 969
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,505,969,120, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
505:5x 101
969:3x 17x 19
120:2x 2x 2x 3x 5
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 3x 5x 19 = 1140
Therefore, the value for common factors is 1140.
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 = 49091090400/(1x1140)
LCM = 49091090400/1140
LCM = 43062360
Thus, we can understand that the LCM of 836,505,969,120 is 43062360.
