Find the smallest 4-digit number which is divisible by 18, 24 and 32.
Answer :
LCM 0f 18, 24 and 32
LCM = 2 × 2 × 2 × 2 × 2 × 3 × 3 = 288
As, 288 is the smallest number divisible by 18, 24 and 32 and we have to find the smallest 4-digit multiple of 288 therefore we have to find the smallest 4-digit multiple of 288.It can be observed that
288 × 3 = 864 and
288 × 4 = 1152
1152 is the smallest 4 digit multiple of 288.Therefore, the smallest 4-digit number which is divisible by 18, 24 and 32 is 1152.
