    The greatest number that will divide 527 and 632 leaving remainders 7 and 8, respectively, is:

    A.

    104

    B.

    112

    C.

    98

    D.

    102

    Correct option is A

    Given:

    Number divides 527 leaving remainder 7

    Number divides 632 leaving remainder 8

    Find the greatest such number.

    Solution:

    Subtract remainders

    527 - 7 = 520

    632 - 8 = 624

    HCF using division:

    624 = 520× 1 + 104

    520 = 104 × 5 + 0

    So,

    HCF = 104
