This is a ridiculous question, due to the fact that 31 is a Prime number. Therefore, as 31 is not a factor of 30, the highest common factor can only be 1.
Special case. 13 and 31 have no common factors other than 1. In such cases, the GCF is 1 and the LCM is their product (403).
The GCF is 1.
The GCF is 1.
The GCF is 1.
GCF(67, 65, 31) = 1.
The greatest common factor of 30 and 39 is 3.
The greatest common factor of 30 , 50 = 10
greatest common factor of 110 and 30 is 10.
The greatest common factor of 16 and 30 is 2
The greatest common factor (GCF) is: 5.
The greatest common factor (GCF) of 20 and 30 is 10.
The greatest common factor of 30 and 39 is 3.
30 is a factor of 150 so 30 is the greatest common factor of 30 and 150
The greatest common factor of 30 , 60 = 30
The greatest common factor of 30 , 50 = 10
The greatest common factor of 7 and 30 is 1.
The Greatest Common Factor of 30, 70: 10
What is the greatest common factor shared by 100 and 30?
The Greatest Common Factor of 30, 40: 10
Since 30 is a factor of 60, and the largest possible factor of 30 is 30, the greatest common factor is 30.
The greatest common factor of 16 and 30 is 2
greatest common factor of 110 and 30 is 10.
