Question

find the lowest number which divided by 30,45 and 60 leaves the remainder of 7 in each case.​

Answer 1

Answer:

Least common multiple of 30, 40 and 60 is 120, which means that 120 is the smallest number which when divided by 30, 40 and 60 leaves 0 as the remainder. Thus, If we add 7 to 120 we will get 127 which when divided by 30, 40 and 60 leaves remainder 7.
