Given numbers are 665,765,614,891,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,765,614,891,865 is 1069948181610.
Find LCM of 665,765,614,891,865 with Prime Factorization
| 3 | 665, 765, 614, 891, 865 |
| 3 | 665, 255, 614, 297, 865 |
| 5 | 665, 85, 614, 99, 865 |
| 133, 17, 614, 99, 173 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 133 x 17 x 614 x 99 x 173 = 1069948181610
Therefore, the lowest common multiple of 665,765,614,891,865 is 1069948181610.
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.
665 x 765 x 614 x 891 x 865 = 240738340862250
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
614 : 1, 2, 307, 614
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,765,614,891,865, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
765:3x 3x 5x 17
614:2x 307
891:3x 3x 3x 3x 11
865:5x 173
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 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 240738340862250/(1x225)
LCM = 240738340862250/225
LCM = 1069948181610
Thus, we can understand that the LCM of 665,765,614,891,865 is 1069948181610.
