That's known as the prime factorization. It's the bottom branch of the factor tree. The prime factorization of 210 is 2 x 3 x 5 x 7.
You use a factor tree, for the 2 denominators. Yes that is correct the answer on the top but it says 2 denominators. This is the real correct way To do Prime Factorization in fractions first prime factorization the numerator and then the denominator. then put the prime factorization of the numerator on top and put the prime factorization of the denominator on the bottom like fractions.
