Given numbers are 978, 987, 302, 518

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

Apply this formula for all numbers.

Step1:

LCM(978, 987) = 321762

GCD(978, 987) = ( 978 x 987 ) / 321762

= 978 / 987

= 978

Step2:

LCM(3, 302) = 906

GCD(3, 302) = ( 3 x 302 ) / 906

= 3 / 302

= 3

Step3:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

So, Greatest Common Divisor of 978, 987, 302, 518 is 1
