Given numbers are 127,901,445,981,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,901,445,981,645 is 2147958992745.
Find LCM of 127,901,445,981,645 with Prime Factorization
| 3 | 127, 901, 445, 981, 645 |
| 5 | 127, 901, 445, 327, 215 |
| 127, 901, 89, 327, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 127 x 901 x 89 x 327 x 43 = 2147958992745
Therefore, the lowest common multiple of 127,901,445,981,645 is 2147958992745.
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.
127 x 901 x 445 x 981 x 645 = 32219384891175
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.
127 : 1, 127
901 : 1, 17, 53, 901
445 : 1, 5, 89, 445
981 : 1, 3, 9, 109, 327, 981
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,901,445,981,645, is 1.
Now, the common factors can be found like this.
127:127
901:17x 53
445:5x 89
981:3x 3x 109
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 32219384891175/(1x15)
LCM = 32219384891175/15
LCM = 2147958992745
Thus, we can understand that the LCM of 127,901,445,981,645 is 2147958992745.
