Find LCM of 255,278,981,638,986 with Prime Factorization
| 2 | 255, 278, 981, 638, 986 |
| 3 | 255, 139, 981, 319, 493 |
| 17 | 85, 139, 327, 319, 493 |
| 29 | 5, 139, 327, 319, 29 |
| 5, 139, 327, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 29 x 5 x 139 x 327 x 11 x 1 = 7394748570
Therefore, the lowest common multiple of 255,278,981,638,986 is 7394748570.
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.
255 x 278 x 981 x 638 x 986 = 43747332540120
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.
255 : 1, 3, 5, 15, 17, 51, 85, 255
278 : 1, 2, 139, 278
981 : 1, 3, 9, 109, 327, 981
638 : 1, 2, 11, 22, 29, 58, 319, 638
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,278,981,638,986, is 1.
Now, the common factors can be found like this.
255:3x 5x 17
278:2x 139
981:3x 3x 109
638:2x 11x 29
986:2x 17x 29
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 3x 17x 29 = 5916
Therefore, the value for common factors is 5916.
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 = 43747332540120/(1x5916)
LCM = 43747332540120/5916
LCM = 7394748570
Thus, we can understand that the LCM of 255,278,981,638,986 is 7394748570.
