Given numbers are 978, 291, 516, 863

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

Apply this formula for all numbers.

Step1:

LCM(978, 291) = 94866

GCD(978, 291) = ( 978 x 291 ) / 94866

= 978 / 291

= 978

Step2:

LCM(3, 516) = 516

GCD(3, 516) = ( 3 x 516 ) / 516

= 3 / 516

= 3

Step3:

LCM(3, 863) = 2589

GCD(3, 863) = ( 3 x 863 ) / 2589

= 3 / 863

= 3

So, Greatest Common Divisor of 978, 291, 516, 863 is 1
