Given numbers are 131,798,931,317
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,798,931,317 is 231969822.
Find LCM of 131,798,931,317 with Prime Factorization
| 7 | 131, 798, 931, 317 |
| 19 | 131, 114, 133, 317 |
| 131, 6, 7, 317 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 131 x 6 x 7 x 317 = 231969822
Therefore, the lowest common multiple of 131,798,931,317 is 231969822.
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.
131 x 798 x 931 x 317 = 30851986326
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.
131 : 1, 131
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
931 : 1, 7, 19, 49, 133, 931
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,798,931,317, is 1.
Now, the common factors can be found like this.
131:131
798:2x 3x 7x 19
931:7x 7x 19
317:317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 30851986326/(1x133)
LCM = 30851986326/133
LCM = 231969822
Thus, we can understand that the LCM of 131,798,931,317 is 231969822.
