Given numbers are 289,989,847,259
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,989,847,259 is 8957344319.
Find LCM of 289,989,847,259 with Prime Factorization
| 7 | 289, 989, 847, 259 |
| 289, 989, 121, 37 |
Multiply the prime numbers at the bottom and the left side.
7 x 289 x 989 x 121 x 37 = 8957344319
Therefore, the lowest common multiple of 289,989,847,259 is 8957344319.
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.
289 x 989 x 847 x 259 = 62701410233
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.
289 : 1, 17, 289
989 : 1, 23, 43, 989
847 : 1, 7, 11, 77, 121, 847
259 : 1, 7, 37, 259
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,989,847,259, is 1.
Now, the common factors can be found like this.
289:17x 17
989:23x 43
847:7x 11x 11
259:7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 62701410233/(1x7)
LCM = 62701410233/7
LCM = 8957344319
Thus, we can understand that the LCM of 289,989,847,259 is 8957344319.
