Given numbers are 165,391,175,605,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,391,175,605,918 is 447088950.
Find LCM of 165,391,175,605,918 with Prime Factorization
| 3 | 165, 391, 175, 605, 918 |
| 5 | 55, 391, 175, 605, 306 |
| 11 | 11, 391, 35, 121, 306 |
| 17 | 1, 391, 35, 11, 306 |
| 1, 23, 35, 11, 18 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 1 x 23 x 35 x 11 x 18 = 447088950
Therefore, the lowest common multiple of 165,391,175,605,918 is 447088950.
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.
165 x 391 x 175 x 605 x 918 = 6270422523750
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
391 : 1, 17, 23, 391
175 : 1, 5, 7, 25, 35, 175
605 : 1, 5, 11, 55, 121, 605
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,391,175,605,918, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
391:17x 23
175:5x 5x 7
605:5x 11x 11
918:2x 3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11x 17 = 14025
Therefore, the value for common factors is 14025.
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 = 6270422523750/(1x14025)
LCM = 6270422523750/14025
LCM = 447088950
Thus, we can understand that the LCM of 165,391,175,605,918 is 447088950.
