Given numbers are 165,393,645,702,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,393,645,702,917 is 1522430910.
Find LCM of 165,393,645,702,917 with Prime Factorization
| 3 | 165, 393, 645, 702, 917 |
| 5 | 55, 131, 215, 234, 917 |
| 131 | 11, 131, 43, 234, 917 |
| 11, 1, 43, 234, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 131 x 11 x 1 x 43 x 234 x 7 = 1522430910
Therefore, the lowest common multiple of 165,393,645,702,917 is 1522430910.
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 393 x 645 x 702 x 917 = 26924190643350
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
393 : 1, 3, 131, 393
645 : 1, 3, 5, 15, 43, 129, 215, 645
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,393,645,702,917, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
393:3x 131
645:3x 5x 43
702:2x 3x 3x 3x 13
917:7x 131
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 5x 131 = 17685
Therefore, the value for common factors is 17685.
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 = 26924190643350/(1x17685)
LCM = 26924190643350/17685
LCM = 1522430910
Thus, we can understand that the LCM of 165,393,645,702,917 is 1522430910.
