Some people use the distributive property to add 24 and 36, but you wouldn't use it to find the GCF which, by the way, is 12.
You need at least two numbers to find a GCF.
(2 x 9) + (3 x 9) = 5 x 9 = 45 The GCF is 9.
40 + 32 = (5 x 8) + (4 x 8) = 9 x 8 = 72
(6 x 7) + (6 x 16) = 6 x 23 = 138
distributive
distributive.
OWO
6 x 4.3 = 6 x 4 + 6 x 0.3 = 24 + 1.8 = 25.8
7*9 = 9*(10 - 3) = 90 - 27 = 63
(7 x 60) + (7 x 5) = 420 + 35 = 455
(7 x 10) + (7 x 4) + (7 x 0.6) = 70 + 28 + 4.2 = 102.2
You don't need to use the distributive property. 3*17 = 51 so 30*17 = 510 Why invoke procedures that are not necessary?
5*43 = 5*(40 + 3) = 5*40 + 5*3 = 200 + 15 = 215
7*46 = 7*(40 + 6) = 7*40 + 7*6 = 280 + 42 = 322

I don't. I learned the 18 times table at school - around 50 years ago - and still recall it.
