75=5 3 5
90=5 3 6
75+90=5 3(5+6)=5 3*11
15 ( 5 + 6 ) ;
To express the sum 75 + 90 as a product using their greatest common factor, we first determine that the GCF is 15. Therefore, we can write 75 + 90 as 15 ( 5 + 6 ) , where 5 and 6 are the results of dividing each number by the GCF. This approach illustrates how sums can be factored using their common factors.
