Find LCM of 273,108,128,840,191 with Prime Factorization
| 2 | 273, 108, 128, 840, 191 |
| 2 | 273, 54, 64, 420, 191 |
| 2 | 273, 27, 32, 210, 191 |
| 3 | 273, 27, 16, 105, 191 |
| 7 | 91, 9, 16, 35, 191 |
| 13, 9, 16, 5, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 9 x 16 x 5 x 191 = 300343680
Therefore, the lowest common multiple of 273,108,128,840,191 is 300343680.
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.
273 x 108 x 128 x 840 x 191 = 605492858880
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
128 : 1, 2, 4, 8, 16, 32, 64, 128
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
191 : 1, 191
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,108,128,840,191, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
108:2x 2x 3x 3x 3
128:2x 2x 2x 2x 2x 2x 2
840:2x 2x 2x 3x 5x 7
191:191
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 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 605492858880/(1x2016)
LCM = 605492858880/2016
LCM = 300343680
Thus, we can understand that the LCM of 273,108,128,840,191 is 300343680.
