Given numbers are 789,981,946,173,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,981,946,173,763 is 295569784818.
Find LCM of 789,981,946,173,763 with Prime Factorization
| 3 | 789, 981, 946, 173, 763 |
| 109 | 263, 327, 946, 173, 763 |
| 263, 3, 946, 173, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 109 x 263 x 3 x 946 x 173 x 7 = 295569784818
Therefore, the lowest common multiple of 789,981,946,173,763 is 295569784818.
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.
789 x 981 x 946 x 173 x 763 = 96651319635486
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.
789 : 1, 3, 263, 789
981 : 1, 3, 9, 109, 327, 981
946 : 1, 2, 11, 22, 43, 86, 473, 946
173 : 1, 173
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,981,946,173,763, is 1.
Now, the common factors can be found like this.
789:3x 263
981:3x 3x 109
946:2x 11x 43
173:173
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 109 = 327
Therefore, the value for common factors is 327.
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 = 96651319635486/(1x327)
LCM = 96651319635486/327
LCM = 295569784818
Thus, we can understand that the LCM of 789,981,946,173,763 is 295569784818.
