Answer :

75=5*3*5
90=5*3*6

75+90=5*3(5+6)=5*3*11

Answer:

[tex]15(5+6)[/tex]

Step-by-step explanation:

gcf of 75 +90

To find GCF lets break the numbers one by one

75 can be written as 5 times 5 times 3

90 can be written as 5 times 2 times 3 times 3

Now we look at the greatest common factor

Both numbers have 5 and 3 in common

So  GCF is 15

we take out 15 that is in common

[tex]15(5+6)[/tex]
