The LCM of 254,187,138,388,836 is 12080356332.
Find LCM of 254,187,138,388,836 with Prime Factorization
| 2 | 254, 187, 138, 388, 836 |
| 2 | 127, 187, 69, 194, 418 |
| 11 | 127, 187, 69, 97, 209 |
| 127, 17, 69, 97, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 127 x 17 x 69 x 97 x 19 = 12080356332
Therefore, the lowest common multiple of 254,187,138,388,836 is 12080356332.
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.
254 x 187 x 138 x 388 x 836 = 2126142714432
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.
254 : 1, 2, 127, 254
187 : 1, 11, 17, 187
138 : 1, 2, 3, 6, 23, 46, 69, 138
388 : 1, 2, 4, 97, 194, 388
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,187,138,388,836, is 1.
Now, the common factors can be found like this.
254:2x 127
187:11x 17
138:2x 3x 23
388:2x 2x 97
836:2x 2x 11x 19
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 11 = 176
Therefore, the value for common factors is 176.
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 = 2126142714432/(1x176)
LCM = 2126142714432/176
LCM = 12080356332
Thus, we can understand that the LCM of 254,187,138,388,836 is 12080356332.
