Given numbers are 318, 261, 239, 978

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

Apply this formula for all numbers.

Step1:

LCM(318, 261) = 27666

GCD(318, 261) = ( 318 x 261 ) / 27666

= 318 / 261

= 318

Step2:

LCM(3, 239) = 717

GCD(3, 239) = ( 3 x 239 ) / 717

= 3 / 239

= 3

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 318, 261, 239, 978 is 1
