The LCM of 768,258,172,127 is 4194048.
Find LCM of 768,258,172,127 with Prime Factorization
| 2 | 768, 258, 172, 127 |
| 2 | 384, 129, 86, 127 |
| 3 | 192, 129, 43, 127 |
| 43 | 64, 43, 43, 127 |
| 64, 1, 1, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 64 x 1 x 1 x 127 = 4194048
Therefore, the lowest common multiple of 768,258,172,127 is 4194048.
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.
768 x 258 x 172 x 127 = 4328257536
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
258 : 1, 2, 3, 6, 43, 86, 129, 258
172 : 1, 2, 4, 43, 86, 172
127 : 1, 127
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,258,172,127, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
258:2x 3x 43
172:2x 2x 43
127:127
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 43 = 1032
Therefore, the value for common factors is 1032.
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 = 4328257536/(1x1032)
LCM = 4328257536/1032
LCM = 4194048
Thus, we can understand that the LCM of 768,258,172,127 is 4194048.
