What least number should be added to 3500 to make it exactly divisible by 42 49 56 and 63?
To find the least number that should be added to 3500 to make it divisible by 42, 49, 56, and 63, we need to find the least common multiple (LCM) of these four numbers. The LCM of 42, 49, 56, and 63 is 1764. To make 3500 divisible by 1764, we need to find the remainder when 3500 is divided by 1764, which is 1972. Therefore, the least number that should be added to 3500 to make it divisible by 42, 49, 56, and 63 is 1764 - 1972 = 208.
