Given numbers are 247,741,831,271
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,741,831,271 is 55624647.
Find LCM of 247,741,831,271 with Prime Factorization
| 3 | 247, 741, 831, 271 |
| 13 | 247, 247, 277, 271 |
| 19 | 19, 19, 277, 271 |
| 1, 1, 277, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 19 x 1 x 1 x 277 x 271 = 55624647
Therefore, the lowest common multiple of 247,741,831,271 is 55624647.
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.
247 x 741 x 831 x 271 = 41217863427
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.
247 : 1, 13, 19, 247
741 : 1, 3, 13, 19, 39, 57, 247, 741
831 : 1, 3, 277, 831
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,741,831,271, is 1.
Now, the common factors can be found like this.
247:13x 19
741:3x 13x 19
831:3x 277
271:271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 19 = 741
Therefore, the value for common factors is 741.
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 = 41217863427/(1x741)
LCM = 41217863427/741
LCM = 55624647
Thus, we can understand that the LCM of 247,741,831,271 is 55624647.
