The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 854 are 2 x 7 x 61

Prime factors of 565 are 5 x 113

Prime factors of 407 are 11 x 37

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

Given numbers are 778, 854, 565, 407

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

Apply this formula for all numbers.

Step1:

LCM(778, 854) = 332206

GCD(778, 854) = ( 778 x 854 ) / 332206

= 778 / 854

= 778

Step2:

LCM(2, 565) = 1130

GCD(2, 565) = ( 2 x 565 ) / 1130

= 2 / 565

= 2

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 778, 854, 565, 407 is 1
