Given numbers are 978, 694, 85, 777

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

Apply this formula for all numbers.

Step1:

LCM(978, 694) = 339366

GCD(978, 694) = ( 978 x 694 ) / 339366

= 978 / 694

= 978

Step2:

LCM(2, 85) = 170

GCD(2, 85) = ( 2 x 85 ) / 170

= 2 / 85

= 2

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 978, 694, 85, 777 is 1
