The list of prime factors of all numbers are

Prime factors of 298 are 2 x 149

Prime factors of 854 are 2 x 7 x 61

Prime factors of 755 are 5 x 151

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 298, 854, 755, 645

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

Apply this formula for all numbers.

Step1:

LCM(298, 854) = 127246

GCD(298, 854) = ( 298 x 854 ) / 127246

= 298 / 854

= 298

Step2:

LCM(2, 755) = 1510

GCD(2, 755) = ( 2 x 755 ) / 1510

= 2 / 755

= 2

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 298, 854, 755, 645 is 1
