Find LCM of 916,682,951,840,120 with Prime Factorization
| 2 | 916, 682, 951, 840, 120 |
| 2 | 458, 341, 951, 420, 60 |
| 2 | 229, 341, 951, 210, 30 |
| 3 | 229, 341, 951, 105, 15 |
| 5 | 229, 341, 317, 35, 5 |
| 229, 341, 317, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 229 x 341 x 317 x 7 x 1 = 20793538920
Therefore, the lowest common multiple of 916,682,951,840,120 is 20793538920.
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 682 x 951 x 840 x 120 = 59885392089600
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
682 : 1, 2, 11, 22, 31, 62, 341, 682
951 : 1, 3, 317, 951
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,682,951,840,120, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
682:2x 11x 31
951:3x 317
840:2x 2x 2x 3x 5x 7
120:2x 2x 2x 3x 5
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 3x 3x 5 = 2880
Therefore, the value for common factors is 2880.
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 = 59885392089600/(1x2880)
LCM = 59885392089600/2880
LCM = 20793538920
Thus, we can understand that the LCM of 916,682,951,840,120 is 20793538920.
