Given numbers are 29, 65, 75, 77

The list of prime factors of all numbers are

Prime factors of 29 are 29

Prime factors of 65 are 5 x 13

Prime factors of 75 are 3 x 5 x 5

Prime factors of 77 are 7 x 11

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

Given numbers are 29, 65, 75, 77

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

Apply this formula for all numbers.

Step1:

LCM(29, 65) = 1885

GCD(29, 65) = ( 29 x 65 ) / 1885

= 29 / 65

= 29

Step2:

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

= 1 / 75

= 1

Step3:

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

= 1 / 77

= 1

So, Greatest Common Divisor of 29, 65, 75, 77 is 1
