Determine the least number when divided by 4,5and 6 leaves remainder 3 in each case.
Here 4-1=3,5-2=3,6-3=3
Since L.C.M (4,5,6)=60
The least number when divided by 4,5and 6 leaves the remainder 3 in each case is L.C.M (4,5,6)=60-3=57
Therefore, the required number is 57.
Question 189
Determine the least number which when divided by 3,4 and 5, leaves remainder 2 in each case.
The least number which when divided by 2,3,4,5 and 6 leaves the remainder1 in each case. If the same number is divided by 7 it leaves no remainder. The number is
