Given numbers are 978, 698, 54, 310

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

Apply this formula for all numbers.

Step1:

LCM(978, 698) = 341322

GCD(978, 698) = ( 978 x 698 ) / 341322

= 978 / 698

= 978

Step2:

LCM(2, 54) = 54

GCD(2, 54) = ( 2 x 54 ) / 54

= 2 / 54

= 2

Step3:

LCM(2, 310) = 310

GCD(2, 310) = ( 2 x 310 ) / 310

= 2 / 310

= 2

So, Greatest Common Divisor of 978, 698, 54, 310 is 2
