The LCM of 831,144,308,368 is 70641648.
Find LCM of 831,144,308,368 with Prime Factorization
| 2 | 831, 144, 308, 368 |
| 2 | 831, 72, 154, 184 |
| 2 | 831, 36, 77, 92 |
| 2 | 831, 18, 77, 46 |
| 3 | 831, 9, 77, 23 |
| 277, 3, 77, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 277 x 3 x 77 x 23 = 70641648
Therefore, the lowest common multiple of 831,144,308,368 is 70641648.
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.
831 x 144 x 308 x 368 = 13563196416
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.
831 : 1, 3, 277, 831
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,144,308,368, is 1.
Now, the common factors can be found like this.
831:3x 277
144:2x 2x 2x 2x 3x 3
308:2x 2x 7x 11
368:2x 2x 2x 2x 23
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 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 13563196416/(1x192)
LCM = 13563196416/192
LCM = 70641648
Thus, we can understand that the LCM of 831,144,308,368 is 70641648.
