Given numbers are 115,247,627,781,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,247,627,781,961 is 63957351315.
Find LCM of 115,247,627,781,961 with Prime Factorization
| 11 | 115, 247, 627, 781, 961 |
| 19 | 115, 247, 57, 71, 961 |
| 115, 13, 3, 71, 961 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 115 x 13 x 3 x 71 x 961 = 63957351315
Therefore, the lowest common multiple of 115,247,627,781,961 is 63957351315.
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.
115 x 247 x 627 x 781 x 961 = 13367086424835
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.
115 : 1, 5, 23, 115
247 : 1, 13, 19, 247
627 : 1, 3, 11, 19, 33, 57, 209, 627
781 : 1, 11, 71, 781
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,247,627,781,961, is 1.
Now, the common factors can be found like this.
115:5x 23
247:13x 19
627:3x 11x 19
781:11x 71
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 13367086424835/(1x209)
LCM = 13367086424835/209
LCM = 63957351315
Thus, we can understand that the LCM of 115,247,627,781,961 is 63957351315.
