Given numbers are 272, 396, 781, 865

The list of prime factors of all numbers are

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 781 are 11 x 71

Prime factors of 865 are 5 x 173

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

Given numbers are 272, 396, 781, 865

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

Apply this formula for all numbers.

Step1:

LCM(272, 396) = 26928

GCD(272, 396) = ( 272 x 396 ) / 26928

= 272 / 396

= 272

Step2:

LCM(4, 781) = 3124

GCD(4, 781) = ( 4 x 781 ) / 3124

= 4 / 781

= 4

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 272, 396, 781, 865 is 1
