find the greatest common factor of 20,22, and 32.
The greatest common factor is?
20 = 2*2*5
22 = 2*11
32 = 2*2*2*2*2
So ..... who is common to all three of them?
What goes into 20, 22, and 32?
Can you find any other number than 2?
I got it I'm so dumb its 2! ;-;
thxs guys!!!
You're welcome.
To find the greatest common factor (GCF) of 20, 22, and 32, we can use the prime factorization method.
Step 1: Prime factorize each number:
- 20 = 2^2 * 5
- 22 = 2 * 11
- 32 = 2^5
Step 2: Now, write down the common prime factors:
Common prime factors: 2 (it appears in the prime factorization of all three numbers)
Step 3: Calculate the GCF by multiplying the common prime factors:
GCF = 2
Therefore, the greatest common factor (GCF) of 20, 22, and 32 is 2.
