    let us take an example... let 'a' =2 and 'b'=3 therefore the product will be \['ab' = 2 \times 3 = 6\] now how many times 2 can be evenly divisible by 3 = ? and how many times 3 can be evenly divisible by 2 = ? (if you relpy or try to provid answer to above questions I will write next steps...because...I don't like to write answer directly) ;)
