The LCM of 845,665,976,676 is 109687760.
Find LCM of 845,665,976,676 with Prime Factorization
| 2 | 845, 665, 976, 676 |
| 2 | 845, 665, 488, 338 |
| 5 | 845, 665, 244, 169 |
| 13 | 169, 133, 244, 169 |
| 13 | 13, 133, 244, 13 |
| 1, 133, 244, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 13 x 1 x 133 x 244 x 1 = 109687760
Therefore, the lowest common multiple of 845,665,976,676 is 109687760.
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.
845 x 665 x 976 x 676 = 370744628800
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.
845 : 1, 5, 13, 65, 169, 845
665 : 1, 5, 7, 19, 35, 95, 133, 665
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,665,976,676, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
665:5x 7x 19
976:2x 2x 2x 2x 61
676:2x 2x 13x 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 5x 13x 13 = 3380
Therefore, the value for common factors is 3380.
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 = 370744628800/(1x3380)
LCM = 370744628800/3380
LCM = 109687760
Thus, we can understand that the LCM of 845,665,976,676 is 109687760.
