Given numbers are 778, 816, 809, 265

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 809 are 809

Prime factors of 265 are 5 x 53

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

Given numbers are 778, 816, 809, 265

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

Apply this formula for all numbers.

Step1:

LCM(778, 816) = 317424

GCD(778, 816) = ( 778 x 816 ) / 317424

= 778 / 816

= 778

Step2:

LCM(2, 809) = 1618

GCD(2, 809) = ( 2 x 809 ) / 1618

= 2 / 809

= 2

Step3:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

So, Greatest Common Divisor of 778, 816, 809, 265 is 1
