Given numbers are 854, 251, 644, 770

The list of prime factors of all numbers are

Prime factors of 854 are 2 x 7 x 61

Prime factors of 251 are 251

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 854, 251, 644, 770

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

Apply this formula for all numbers.

Step1:

LCM(854, 251) = 214354

GCD(854, 251) = ( 854 x 251 ) / 214354

= 854 / 251

= 854

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 854, 251, 644, 770 is 1
