The GCF is 18.
The GCF is 2.
The mistake is that there is a greater common factor than 18. It's 36. 36 divides 36 evenly. 36 divides 72 evenly.
The GCF is 18.
90 = 18 x 5 36 = 18 x 2 Since 90 and 36 are both divisible by 18, the GCF is 18.
No.
No, the GCF of any two numbers can't get greater than the smaller of the two numbers.
No. 18 doesn't have a factor greater than itself.
The GCF is 18.
No, the GCF of two numbers can never be greater than the smaller number.
The GCF of 18 and 36 is 18.
No, since GCF stands for greatest common factor, and there is no number over 18 that when divided to 18 and 36 will the answer be a whole number.
The GCF is 18.
The GCF is 18.
It would be 18.
The GCF is 18.
The GCF is 6.
