Given numbers are 165,504,553,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,504,553,505 is 221177880.
Find LCM of 165,504,553,505 with Prime Factorization
| 3 | 165, 504, 553, 505 |
| 5 | 55, 168, 553, 505 |
| 7 | 11, 168, 553, 101 |
| 11, 24, 79, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 24 x 79 x 101 = 221177880
Therefore, the lowest common multiple of 165,504,553,505 is 221177880.
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 504 x 553 x 505 = 23223677400
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
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
553 : 1, 7, 79, 553
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,504,553,505, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
504:2x 2x 2x 3x 3x 7
553:7x 79
505:5x 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 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 23223677400/(1x105)
LCM = 23223677400/105
LCM = 221177880
Thus, we can understand that the LCM of 165,504,553,505 is 221177880.
