Question

1. Find the least number which when divided by 16, 18, 24 leaves the remainder 4,
but there is no remainder when it devided by 7.​

Answer 1

Answer:

When the number is divided by 16, 18, 20 and 25, the remainder is 4 in each case. (2) When the number is divided by 7, the remainder should be 0. To satisfy first condition, we need to compute LCM of 16, 18, 20 and 25. LCM of these numbers is 3600.
