Least number when divided by 12, 16, 24, 36 & leaves remainder 0 = LCM of 12, 16, 24, 36 So, LCM leaves remainder 0 Now, in the question We are asked smallest number which leaves remainder 7 So, Required number will be 7 more than LCM ∴ Required number = LCM + 7 Finding LCM of 12, 16, 24, 36 ∴ LCM = 2 × 2 × 2 × 2 × 3 × 3 = 16 × 9 = 144 So, Required Number = LCM + 7 = 144 + 7 = 151 `151``121``141``111` Answer : A Solution : To solve this question, we first have to find `LCM` of `12,16,24 and 36`. Find the least number which when divided by 12, 16, 24 and 36 leaves a remainder 7 in each case. SolutionWe first find the LCM of 12, 16, 24, and 36 as follows: Thus, LCM = 2 × 2 × 2 × 2 × 3 × 3 = 144 144 is the least number which when divided by the given numbers will leave remainder 0 in each case. But
we need the least number that leaves remainder 7in each case. The required least number = 144 + 7 = 151. Concept: Lowest Common Multiple Is there an error in this question or solution? What is the least number which when divided by 12 16 24 36 leaves a remainder 7 in each case?Least Number which when divided by 12, 16 ,24 and 36 leaves a remainder 7 in each case =144+7=151.
What is the least number when divided by 36 24 and 16 leaves 11 as remainder in each case?This is Expert Verified Answer
∴ 155 is the least number when divided by 36, 24 and 16 leaves 11 as remainder in each case.
What is the least number which when divided by 12 15 18 24 and 36 will leave 7 as remainder in each case?Hence, the smallest number is 360. Q.
What is the least number which when divided by 12 24 and 30 leaves a remainder 7 in each case?The smallest number which divides 12 16 24 and 36 is 144. But we have a condition that it leaves a remainder of 7. So we add 7 to the LCM (144+7=151). Hence the smallest number that when divided by 12 16 24 and 36 leaves a remainder 7 is 151.
