GCD of numbers is the greatest common divisor

So, the GCD (91, 80, 73, 97) = 1.

Given numbers are 91, 80, 73, 97

The list of prime factors of all numbers are

Prime factors of 91 are 7 x 13

Prime factors of 80 are 2 x 2 x 2 x 2 x 5

Prime factors of 73 are 73

Prime factors of 97 are 97

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 91, 80, 73, 97

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(91, 80) = 7280

GCD(91, 80) = ( 91 x 80 ) / 7280

= 91 / 80

= 91

Step2:

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

= 1 / 73

= 1

Step3:

LCM(1, 97) = 97

GCD(1, 97) = ( 1 x 97 ) / 97

= 1 / 97

= 1

So, Greatest Common Divisor of 91, 80, 73, 97 is 1
