Answer:
36
Step-by-step explanation:
GCF or greatest common factor is the greater/biggest number that can factor for both numbers. To find GCF, you need to make factor of both number
72- 2 * 2 * 2 * 3 * 3 = 2^3 * 3^2
36= 2 * 2 * 3 * 3 = 2^2 * 3^2
After this, you can compare the factor of both numbers. Both numbers can be divided by 2, but 36 can be divided 2 times while 72 can be divided 3 times. In this case, you take the lowest number which is 2. Both numbers can be divided by 3^2 so you can take it whole.
The factor will be: 2^2 * 3 *2= 4 * 9= 36
Elaborate? i will try to help!

Step-by-step explanation:
Answer: yes, it is
Step-by-step explanation:
A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.
n = k(k+1)(k-1)
If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.
Now, if k-1 is a multiple of 3, it can be even or odd.
if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6
if k-1 is odd, then k and k+1 is even, hence, divisible by 2.
As n = k(k+1)(k-1), n is also divisible by 6.
Hello There!
It would be 9(3w + 4) (3w + 4)
