This is tricky. Once you determine that 73 is a prime number then you can ignore 127 (since 73 is not a factor of 127). So, the greatest common factor is 1. Note: if you asked 73 and 146 then the answer would be 73. Anytime one of the numbers is a prime - then the answer is EITHER 1 or the prime number (if the other number is a multiple of the prime).
The greatest common factor of 73 , 35 = 1
The greatest common factor of 11 and 73 is 1.
The greatest common factor of 6 and 73 is 1.
The greatest common factor of 27 and 73 is 1.
The only common and least common factor is: 1
The greatest common factor of 73 and 88 is 1.
The GCF is 1.
The greatest common factor of 26 and 73 is 1
73 is a prime number so 51,3x17 and 73 only have the number 1 as the greatest common factor.
The Answer:The easier way is to prime factorize the 2 numbers. However, since both values are prime, we automatically deduce that the GCF of 73 and 127 is 1.
The common factors of 29 are: 1, and 29. The common factors of 73 are: 1, and 73. They are both prime numbers so the greatest common factor is 1.
