Given numbers are 165,923,165,689,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,923,165,689,728 is 452011560.
Find LCM of 165,923,165,689,728 with Prime Factorization
| 3 | 165, 923, 165, 689, 728 |
| 5 | 55, 923, 55, 689, 728 |
| 11 | 11, 923, 11, 689, 728 |
| 13 | 1, 923, 1, 689, 728 |
| 1, 71, 1, 53, 56 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 1 x 71 x 1 x 53 x 56 = 452011560
Therefore, the lowest common multiple of 165,923,165,689,728 is 452011560.
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 923 x 165 x 689 x 728 = 12604342350600
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
923 : 1, 13, 71, 923
165 : 1, 3, 5, 11, 15, 33, 55, 165
689 : 1, 13, 53, 689
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,923,165,689,728, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
923:13x 71
165:3x 5x 11
689:13x 53
728:2x 2x 2x 7x 13
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 11x 13x 13 = 27885
Therefore, the value for common factors is 27885.
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 = 12604342350600/(1x27885)
LCM = 12604342350600/27885
LCM = 452011560
Thus, we can understand that the LCM of 165,923,165,689,728 is 452011560.
