To find the LCM of any group of numbers, first factor each number into primes. Then, find the most number of times each prime is factored into a number. Finally, multiply all those numbers.

The prime factorization of 25 is 5x5.

For 30, it is 2x3x5.

For 36, it is 2x2x3x3.

5 is multiplied a maximum of two times (in 25), 3 is multiplied two times (in 36), and 2 is multiplied two times (in 36). We find 2x2x3x3x5x5, which is 900.

So the LCM of 25, 30, and 36 is 900.
