Question
What is the smallest number which when divided by 24,36 and 54 gives a remainder of 5 each time?
Hard Open in App Solution Verified by Toppr Let's factorize, 24 = 2x2x2x3 36 = 2x2x3x3 54 = 2x3x3x3
The smallest number divisible by all 24, 36, 54 is:
LCM(24, 36, 54) = 216
Thus, to get 5 as remainder, we need to add 5 to 216.
(as 216 is the smallest number which gives remainder 0 when divided by 24 or 36 or 54)
216 + 5 = 221
For 12, 221 gives 18 as quotient and 5 as remainder
For 36, 221 gives 6 as quotient and 5 as remainder
For 54, 221 gives 4 as quotient and 5 as remainder
Hence, 221 is required number.

Given∶A number when divided by 48 and 60, leaves a remainder 7 in each case.
But when divided by 13 leaves no remainder.
Formula Used∶Concept of LCM and Hit and Trial method
Calculation∶LCM of 48 and 60 = 24 × 3 × 5 = 240
Let the required number be N
So, N = 240 × x + 7
Now use Hit and Trial method
When, x = 1
Then, N = 240 × 1 + 7 = 240 + 7 = 247
Hence, sum of the digits = 2 + 4 + 7 = 13
∴ 13 is the sum of the digits in the required smallest number which when divided by 48 and 60 leaves a remainder 7, but when divided by 13, the remainder is zero.Download Solution PDF

What is the smallest natural number which when divided by 24, 18, 40 and 60 leave remainder 8 in each case?
Answer (1 of 6): LCM is the least no. /Smallest no. Which is divisible by all the given numbers. So, LCM of 24= 2× 2×2×3, 18= 2×3×3, 40= 2×2×2×5, 60=2×2×3×5, is all factors with greatest power, so LCM = 2^3 ×3^2 ×5^1= 8×9× 5 = 360. So , no. Leaves remainder 8 in each case is 360+8 = 368.

Such a number would be 8 greater than a number that is divisible by all those numbers. Since we want the smallest, answer is 0+8.

prime factors of 24,18,40 and 60 are:
24=2^3*3 18=2*3^2 40=2^3*5 60=2^2*3*5
Thus L;CM (24,18,40,60)=2^3 *3^2*5
=8*9*5=360
THE REMAINDER IN ALL CASES IS 8
HENCE THE NUMBER=LCM+8=368

Using the J programming language:
a#~*./8=18 24 40 60|/a=.1+i.1e3
8 368 728
There are three answers in the range 1–1000. The smallest is 8, as 8 divided by any larger number has a remainder of 8 (and a dividend of 0). So the answer is 8. The next-largest integer is 368 that meets all the criteria.
