Given numbers are 978, 326, 641, 997

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

Apply this formula for all numbers.

Step1:

LCM(978, 326) = 978

GCD(978, 326) = ( 978 x 326 ) / 978

= 978 / 326

= 978

Step2:

LCM(326, 641) = 208966

GCD(326, 641) = ( 326 x 641 ) / 208966

= 326 / 641

= 326

Step3:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

So, Greatest Common Divisor of 978, 326, 641, 997 is 1
