The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 313 are 313

Prime factors of 682 are 2 x 11 x 31

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 978, 313, 682, 648

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

Apply this formula for all numbers.

Step1:

LCM(978, 313) = 306114

GCD(978, 313) = ( 978 x 313 ) / 306114

= 978 / 313

= 978

Step2:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 978, 313, 682, 648 is 1
