    I think the answer is 16 groups.
    My reasoning was to take each number to their prime factorization, so:
    2 to the 4 is the least common multiple and its 16, so 16 groups:
    Each of this 16 groups would have: 2 tambourinists, 5 triangle beaters, 4 drummers, 7 maracas shakers and 3 singers.
    Cool!!

    Dont know if I did this one too quickly and I am wrong but
    16 groups each with
    2 tambourinists, 5 triangle beaters, 4 drummers, 7 maraca shakers and 3 singers


    I looked for the HIGHEST common denominator..

    16 groups of 2 tambourinists, 5 triangle beaters, 4 drummers, 7 maracas shakers, and 3 singers. Simple factoring problem.

    16 (the greatest common factor)


    16 * 2 = 32
    16 * 3 = 48
    16 * 4 = 64
    16 * 5 = 80
    16 * 7 = 112

    16.
    The GCF of all the numbers is 16. Each group has 2 tambourinists, 5 triangle beaters, 4 drummers, 7 maracas shakers, and 3 singers.

    There can be 16 groups (Each group has 2 tambourinists, 5 triangle beaters, 4 drummers, 7 maracas shakers, and 3 singers).

    The largest number is 16

    16 groups as 16 is the greatest common divisor to 32, 48, 64, 80, and 112

    The maximum number of groups is 16 – giving 2 tambourine shakers, 5 triangle players, 4 drummers. 7 maracas shakers, and 3 singers per group.

    Sounds like 16 groups with 21 musicians in each group.

    16. It’s the greatest common factor.


    Each group will have 2 tambourinists, 5 triangle beaters, 4 drummers, 7 maracas shakers, and 3 singers.
