Given numbers are 121,727,486,394,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,727,486,394,197 is 8422136514.
Find LCM of 121,727,486,394,197 with Prime Factorization
2 | 121, 727, 486, 394, 197 |
197 | 121, 727, 243, 197, 197 |
121, 727, 243, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 197 x 121 x 727 x 243 x 1 x 1 = 8422136514
Therefore, the lowest common multiple of 121,727,486,394,197 is 8422136514.
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.
121 x 727 x 486 x 394 x 197 = 3318321786516
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.
121 : 1, 11, 121
727 : 1, 727
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
394 : 1, 2, 197, 394
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,727,486,394,197, is 1.
Now, the common factors can be found like this.
121:11x 11
727:727
486:2x 3x 3x 3x 3x 3
394:2x 197
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 197 = 394
Therefore, the value for common factors is 394.
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 = 3318321786516/(1x394)
LCM = 3318321786516/394
LCM = 8422136514
Thus, we can understand that the LCM of 121,727,486,394,197 is 8422136514.
