Question

find the smallest number which when decreased by 3 is exactly divisible by the number 18,36,45.​

Answer 1

Answer:

864

Step-by-step explanation:

First of all we find the LCM of 18, 36, 32 and 27.

18=2×3×3

36=2×2×3×3

32=2×2×2×2×2

27=3×3×3

LCM=864

864 is the smallest integer which is divisible by 18, 36, 32 and 27.

Hence the smallest integer which needs to be decreased by 3 is 864 + 3 = 867.

867 when decreased by 3 will be divisible by 18, 36, 32 and 27.

hope it helps you
