Given numbers are 197,981,663,402,377
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,981,663,402,377 is 165970271142.
Find LCM of 197,981,663,402,377 with Prime Factorization
| 3 | 197, 981, 663, 402, 377 |
| 13 | 197, 327, 221, 134, 377 |
| 197, 327, 17, 134, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 197 x 327 x 17 x 134 x 29 = 165970271142
Therefore, the lowest common multiple of 197,981,663,402,377 is 165970271142.
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.
197 x 981 x 663 x 402 x 377 = 19418521723614
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.
197 : 1, 197
981 : 1, 3, 9, 109, 327, 981
663 : 1, 3, 13, 17, 39, 51, 221, 663
402 : 1, 2, 3, 6, 67, 134, 201, 402
377 : 1, 13, 29, 377
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,981,663,402,377, is 1.
Now, the common factors can be found like this.
197:197
981:3x 3x 109
663:3x 13x 17
402:2x 3x 67
377:13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 19418521723614/(1x117)
LCM = 19418521723614/117
LCM = 165970271142
Thus, we can understand that the LCM of 197,981,663,402,377 is 165970271142.
