Find LCM of 916,891,981,312,103 with Prime Factorization
| 2 | 916, 891, 981, 312, 103 |
| 2 | 458, 891, 981, 156, 103 |
| 3 | 229, 891, 981, 78, 103 |
| 3 | 229, 297, 327, 26, 103 |
| 229, 99, 109, 26, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 229 x 99 x 109 x 26 x 103 = 238237568712
Therefore, the lowest common multiple of 916,891,981,312,103 is 238237568712.
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.
916 x 891 x 981 x 312 x 103 = 25729657420896
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.
916 : 1, 2, 4, 229, 458, 916
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
981 : 1, 3, 9, 109, 327, 981
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
103 : 1, 103
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,891,981,312,103, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
891:3x 3x 3x 3x 11
981:3x 3x 109
312:2x 2x 2x 3x 13
103:103
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 25729657420896/(1x108)
LCM = 25729657420896/108
LCM = 238237568712
Thus, we can understand that the LCM of 916,891,981,312,103 is 238237568712.
