1. Prime factorize each number:
5 = 5
15 = 3 \times 5
25 = 5^2
2. Take the highest power of each prime number present:
\text{Highest power of } 3 = 3
\text{Highest power of } 5 = 5^2
3. Multiply these highest powers together to find the LCM:
3 \times 5^2 = 3 \times 25 = 75
Thus, the LCM of 5, 15, and 25 is \text{LCM}(5, 15, 25) = 75
