The GCF is 1.
The GCF of 2, 9 and 11 is 1. The LCM is 198.
The GCF is 1.
The GCF is 1.
The GCF of 9 and 11 is 1.The factors of 9 are 1, 3, 9.The factors of 11 are 1, 11.The GCF of 9 and 11 = 1.Has to be 1 cuz 11 is prime
The GCF is 1.
The GCF is 11.
9 since 9 * 3 = 27 and 9 * 11 = 99
You need at least two numbers to find a GCF. If that's 11 and 9, the GCF is 1.
The GCF of 27 and 99 is 9 3 x 9 = 27, 11 x 9 = 99
The GCF is 1.
' 1 ' is the only common factor of those numbers.
If the GCF of 11 and x is 1 and the LCM of 11 and x is 99, x= 9.
