Given numbers are 978, 970, 680, 239

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 970 are 2 x 5 x 97

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 239 are 239

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

Given numbers are 978, 970, 680, 239

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

Apply this formula for all numbers.

Step1:

LCM(978, 970) = 474330

GCD(978, 970) = ( 978 x 970 ) / 474330

= 978 / 970

= 978

Step2:

LCM(2, 680) = 680

GCD(2, 680) = ( 2 x 680 ) / 680

= 2 / 680

= 2

Step3:

LCM(2, 239) = 478

GCD(2, 239) = ( 2 x 239 ) / 478

= 2 / 239

= 2

So, Greatest Common Divisor of 978, 970, 680, 239 is 1
