Construct a factor tree for the given number.
5) 392

  • math -

    Keep dividing by any factors until you get to the prime factors.

    2 goes into 392.
    392/2 = 196
    2 goes into 196
    196/2 = 98
    2 goes into 98
    98/2 = 49
    So far we have 2^3, because we divided by 2 three times.
    Now, 7 goes into 49.
    49/7 = 7.
    Therefore, we have 7^2 and 2^3 as the prime factors

  • math -

    392
    | \
    196 2
    | \
    98 2
    | \
    49 2
    | \
    7 7
    therefore
    392 = 2.2.2.7.7
