Given numbers are 165,203,355,454,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,203,355,454,261 is 3239033490.
Find LCM of 165,203,355,454,261 with Prime Factorization
| 3 | 165, 203, 355, 454, 261 |
| 5 | 55, 203, 355, 454, 87 |
| 29 | 11, 203, 71, 454, 87 |
| 11, 7, 71, 454, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 29 x 11 x 7 x 71 x 454 x 3 = 3239033490
Therefore, the lowest common multiple of 165,203,355,454,261 is 3239033490.
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 203 x 355 x 454 x 261 = 1408979568150
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
203 : 1, 7, 29, 203
355 : 1, 5, 71, 355
454 : 1, 2, 227, 454
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,203,355,454,261, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
203:7x 29
355:5x 71
454:2x 227
261:3x 3x 29
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 29 = 435
Therefore, the value for common factors is 435.
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 = 1408979568150/(1x435)
LCM = 1408979568150/435
LCM = 3239033490
Thus, we can understand that the LCM of 165,203,355,454,261 is 3239033490.
