The list of prime factors of all numbers are

Prime factors of 475 are 5 x 5 x 19

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 957 are 3 x 11 x 29

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 475, 980, 957, 978

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

Apply this formula for all numbers.

Step1:

LCM(475, 980) = 93100

GCD(475, 980) = ( 475 x 980 ) / 93100

= 475 / 980

= 475

Step2:

LCM(5, 957) = 4785

GCD(5, 957) = ( 5 x 957 ) / 4785

= 5 / 957

= 5

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 475, 980, 957, 978 is 1
