Given numbers are 991,273,527,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,273,527,217 is 142576161.
Find LCM of 991,273,527,217 with Prime Factorization
| 7 | 991, 273, 527, 217 |
| 31 | 991, 39, 527, 31 |
| 991, 39, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 31 x 991 x 39 x 17 x 1 = 142576161
Therefore, the lowest common multiple of 991,273,527,217 is 142576161.
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.
991 x 273 x 527 x 217 = 30939026937
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.
991 : 1, 991
273 : 1, 3, 7, 13, 21, 39, 91, 273
527 : 1, 17, 31, 527
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,273,527,217, is 1.
Now, the common factors can be found like this.
991:991
273:3x 7x 13
527:17x 31
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 31 = 217
Therefore, the value for common factors is 217.
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 = 30939026937/(1x217)
LCM = 30939026937/217
LCM = 142576161
Thus, we can understand that the LCM of 991,273,527,217 is 142576161.
