The LCM of 418,836,824,515 is 861080.
Find LCM of 418,836,824,515 with Prime Factorization
| 2 | 418, 836, 824, 515 |
| 2 | 209, 418, 412, 515 |
| 11 | 209, 209, 206, 515 |
| 19 | 19, 19, 206, 515 |
| 103 | 1, 1, 206, 515 |
| 1, 1, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 103 x 1 x 1 x 2 x 5 = 861080
Therefore, the lowest common multiple of 418,836,824,515 is 861080.
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.
418 x 836 x 824 x 515 = 148291753280
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
824 : 1, 2, 4, 8, 103, 206, 412, 824
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,836,824,515, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
836:2x 2x 11x 19
824:2x 2x 2x 103
515:5x 103
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 11x 19x 103 = 172216
Therefore, the value for common factors is 172216.
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 = 148291753280/(1x172216)
LCM = 148291753280/172216
LCM = 861080
Thus, we can understand that the LCM of 418,836,824,515 is 861080.
