Given numbers are 217,285,815,986,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,285,815,986,129 is 427403002530.
Find LCM of 217,285,815,986,129 with Prime Factorization
3 | 217, 285, 815, 986, 129 |
5 | 217, 95, 815, 986, 43 |
217, 19, 163, 986, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 217 x 19 x 163 x 986 x 43 = 427403002530
Therefore, the lowest common multiple of 217,285,815,986,129 is 427403002530.
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.
217 x 285 x 815 x 986 x 129 = 6411045037950
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.
217 : 1, 7, 31, 217
285 : 1, 3, 5, 15, 19, 57, 95, 285
815 : 1, 5, 163, 815
986 : 1, 2, 17, 29, 34, 58, 493, 986
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,285,815,986,129, is 1.
Now, the common factors can be found like this.
217:7x 31
285:3x 5x 19
815:5x 163
986:2x 17x 29
129:3x 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 = 6411045037950/(1x15)
LCM = 6411045037950/15
LCM = 427403002530
Thus, we can understand that the LCM of 217,285,815,986,129 is 427403002530.
