572=2x286=2x2x143=2x2x11x13
66 33,2 11,3,2
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.
2x2x222
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.
1997 is already prime; no tree.
51 3,17
350=2x5x5x7
a prime factorization tree
33 11,3
The prime factorization of 97 is 97 itself, as it is a prime number and cannot be divided evenly by any other numbers. Therefore, there is no prime factorization tree for the number 97.
50 25,2 5,5,2
131 is already prime. No tree.
585 195,3 65,3,3 13,5,3,3
141 = 3 x 47
572=2x286=2x2x143=2x2x11x13
3 is already prime. No need for a tree.
