Given numbers are 505,171,843,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,171,843,909 is 24265755.
Find LCM of 505,171,843,909 with Prime Factorization
| 3 | 505, 171, 843, 909 |
| 3 | 505, 57, 281, 303 |
| 101 | 505, 19, 281, 101 |
| 5, 19, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 101 x 5 x 19 x 281 x 1 = 24265755
Therefore, the lowest common multiple of 505,171,843,909 is 24265755.
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.
505 x 171 x 843 x 909 = 66172713885
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.
505 : 1, 5, 101, 505
171 : 1, 3, 9, 19, 57, 171
843 : 1, 3, 281, 843
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,171,843,909, is 1.
Now, the common factors can be found like this.
505:5x 101
171:3x 3x 19
843:3x 281
909:3x 3x 101
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 3x 101 = 2727
Therefore, the value for common factors is 2727.
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 = 66172713885/(1x2727)
LCM = 66172713885/2727
LCM = 24265755
Thus, we can understand that the LCM of 505,171,843,909 is 24265755.
