The LCM of 781,836,408,534 is 538833768.
Find LCM of 781,836,408,534 with Prime Factorization
| 2 | 781, 836, 408, 534 |
| 2 | 781, 418, 204, 267 |
| 3 | 781, 209, 102, 267 |
| 11 | 781, 209, 34, 89 |
| 71, 19, 34, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 71 x 19 x 34 x 89 = 538833768
Therefore, the lowest common multiple of 781,836,408,534 is 538833768.
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.
781 x 836 x 408 x 534 = 142252114752
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.
781 : 1, 11, 71, 781
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
534 : 1, 2, 3, 6, 89, 178, 267, 534
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,836,408,534, is 1.
Now, the common factors can be found like this.
781:11x 71
836:2x 2x 11x 19
408:2x 2x 2x 3x 17
534:2x 3x 89
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 142252114752/(1x264)
LCM = 142252114752/264
LCM = 538833768
Thus, we can understand that the LCM of 781,836,408,534 is 538833768.
