It's not necessary. Since 12 is a factor of 72, it is automatically the GCF.
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.
3(5 + 12)
The GCF of 12 and 20 is 4. The distributive property states that 12 x 20 = 10 x 20 + 2 x 20 = 200 + 40 = 240 4(3 + 5)
9(9 + 3) = (9 x 9) + (3 x 9) = 12 x 9 = 108
40 + 44 = (4 x 10) + (4 x 11) = 4 x 21 = 84

The GCF of 12 and 20 is 4. The distributive property states that 12 x 20 = 10 x 20 + 2 x 20 = 200 + 40 = 240 4(3 + 5)
GCF(16, 12) = 4. The distributive property is an attribute of two mathematical operations - not of numbers.
9(9 + 3) = (9 x 9) + (3 x 9) = 12 x 9 = 108
24 + 36 = (2 x 12) + (3 x 12) = 5 x 12 = 60
The distributive property of multiplication over addition is a*(b + c) = a*b + a*c GCF(12, 24) = 12.
40 + 44 = (4 x 10) + (4 x 11) = 4 x 21 = 84

2(x+6)=2x+12. This is an example of the distributive property.
12*56 Use the distributive property on 12: (10+2)*56 = 10*56 + 2*56 Use the distributive property on 56 twice: 10*(50+6) + 2*(50+6) = 10*50 + 10*6 + 2*50 + 2*6 = 500 + 60 + 100 + 12 = 672
