Given numbers are 77, 27, 29, 85

The list of prime factors of all numbers are

Prime factors of 77 are 7 x 11

Prime factors of 27 are 3 x 3 x 3

Prime factors of 29 are 29

Prime factors of 85 are 5 x 17

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

Given numbers are 77, 27, 29, 85

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

Apply this formula for all numbers.

Step1:

LCM(77, 27) = 2079

GCD(77, 27) = ( 77 x 27 ) / 2079

= 77 / 27

= 77

Step2:

LCM(1, 29) = 29

GCD(1, 29) = ( 1 x 29 ) / 29

= 1 / 29

= 1

Step3:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

So, Greatest Common Divisor of 77, 27, 29, 85 is 1
