The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 995 are 5 x 199

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

Given numbers are 978, 672, 855, 995

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

Apply this formula for all numbers.

Step1:

LCM(978, 672) = 109536

GCD(978, 672) = ( 978 x 672 ) / 109536

= 978 / 672

= 978

Step2:

LCM(6, 855) = 1710

GCD(6, 855) = ( 6 x 855 ) / 1710

= 6 / 855

= 6

Step3:

LCM(3, 995) = 2985

GCD(3, 995) = ( 3 x 995 ) / 2985

= 3 / 995

= 3

So, Greatest Common Divisor of 978, 672, 855, 995 is 1
