Given numbers are 865, 791, 169, 636

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 791 are 7 x 113

Prime factors of 169 are 13 x 13

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 865, 791, 169, 636

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

Apply this formula for all numbers.

Step1:

LCM(865, 791) = 684215

GCD(865, 791) = ( 865 x 791 ) / 684215

= 865 / 791

= 865

Step2:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 865, 791, 169, 636 is 1
