Prime Factorization = Divide by factors that are prime number
147 ÷  3 = 49
49 ÷ 7 = 7
7 ÷ 7 = 1
 
147 = 3 x 7 x 7
147 = 3 x 7²

For the parallel lines 1/2 the vertical line is 1 & the horizontal line is 2 so if you multiply both of them should equal 3. I don't acually know about the other one though
