Given numbers are 85, 77, 91, 22

The list of prime factors of all numbers are

Prime factors of 85 are 5 x 17

Prime factors of 77 are 7 x 11

Prime factors of 91 are 7 x 13

Prime factors of 22 are 2 x 11

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

Given numbers are 85, 77, 91, 22

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

Apply this formula for all numbers.

Step1:

LCM(85, 77) = 6545

GCD(85, 77) = ( 85 x 77 ) / 6545

= 85 / 77

= 85

Step2:

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

= 1 / 91

= 1

Step3:

LCM(1, 22) = 22

GCD(1, 22) = ( 1 x 22 ) / 22

= 1 / 22

= 1

So, Greatest Common Divisor of 85, 77, 91, 22 is 1
