  1. What is the greatest number that will divide 2930 and 3246 that will leave 7 as remainder in each case.
    1. 79
    2. 89
    3. 69
    4. 97
Correct Option: A

Obviously, the greatest number will divide completely the numbers (2930 – 7) and (3246 – 7),
i.e., 2923 and 3239.
Hence, the greatest number will be the HCF of 2923 and 3239.

∴ HCF = 79
Hence, the required number = 79
