The LCM of 48,96,91,51,687 is 34009248.
Find LCM of 48,96,91,51,687 with Prime Factorization
| 2 | 48, 96, 91, 51, 687 |
| 2 | 24, 48, 91, 51, 687 |
| 2 | 12, 24, 91, 51, 687 |
| 2 | 6, 12, 91, 51, 687 |
| 3 | 3, 6, 91, 51, 687 |
| 1, 2, 91, 17, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 1 x 2 x 91 x 17 x 229 = 34009248
Therefore, the lowest common multiple of 48,96,91,51,687 is 34009248.
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.
48 x 96 x 91 x 51 x 687 = 14691995136
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.
48 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
96 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
91 : 1, 7, 13, 91
51 : 1, 3, 17, 51
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 48,96,91,51,687, is 1.
Now, the common factors can be found like this.
48:2x 2x 2x 2x 3
96:2x 2x 2x 2x 2x 3
91:7x 13
51:3x 17
687:3x 229
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 14691995136/(1x432)
LCM = 14691995136/432
LCM = 34009248
Thus, we can understand that the LCM of 48,96,91,51,687 is 34009248.
