Find LCM of 271,888,128,972,778 with Prime Factorization
| 2 | 271, 888, 128, 972, 778 |
| 2 | 271, 444, 64, 486, 389 |
| 2 | 271, 222, 32, 243, 389 |
| 3 | 271, 111, 16, 243, 389 |
| 271, 37, 16, 81, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 271 x 37 x 16 x 81 x 389 = 121321245312
Therefore, the lowest common multiple of 271,888,128,972,778 is 121321245312.
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.
271 x 888 x 128 x 972 x 778 = 23293679099904
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.
271 : 1, 271
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
128 : 1, 2, 4, 8, 16, 32, 64, 128
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,888,128,972,778, is 1.
Now, the common factors can be found like this.
271:271
888:2x 2x 2x 3x 37
128:2x 2x 2x 2x 2x 2x 2
972:2x 2x 3x 3x 3x 3x 3
778:2x 389
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 = 23293679099904/(1x192)
LCM = 23293679099904/192
LCM = 121321245312
Thus, we can understand that the LCM of 271,888,128,972,778 is 121321245312.
