"The three" is wrong. There is not a single solution to this problem, but infinitely many. Take any three multiples of 5 - multiplying 5 by numbers that don't share common factors. For example, three different prime numbers.
5, 10 and 15
The GCF of these three numbers is 5.
The GCF of the given three numbers is 5
Since the number 5 is prime, the Greatest Common Factor of the three numbers is 1.
The GCF is 1.
The GCF is 5.
5,10 15,20 25,30 and many more
The GCF of 5 and 10 is 5.
The GCF is 5.
7 is not the greatest common factor (GCF) of 15, 30, and 35 because 7 does not evenly divide into all three numbers. The GCF is the largest number that can divide all three numbers without leaving a remainder, and in this case, the GCF is actually 5 since 5 divides evenly into all three numbers.
The GCF is 5.
The GCF of the given three numbers is 1
The GCF is 1.
