Find the least number divisible by 16, 18 and 32.
288
The required number is the LCM of 16, 18 and 32.
Prime factorising: \(16 = 2^4\), \(18 = 2\times3^2\), \(32 = 2^5\).
LCM takes the highest powers of each prime: \(2^5\times3^2 = 32\times9 = 288\).
The least number divisible by 16, 18 and 32 is 288.
