What is the prime factorization of 1,050

  • 6th grade math -

    Let's start by factoring out the obvious 50.

    1050 = 50 * 21
    The prime favors of 50 are 5*5*2
    The prime factors of 21 are 3*7

    The prime factors of 1050 are therefore
    2*3*5*5*7

    You could have done this problem other ways, but you'd get the same answer.

    1050/2=525
    525/5=105
    105/5=21
    21/7=3


    all primes are 2,3,5,5,7

    Have you ever tried factor trees?
    1050
    50 21
    5 10 7 3
    5 2

    Factors: 5 5 2 7 3
    These are fairly quick. Good luck!
