Given numbers are 978, 796, 187, 921

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

Apply this formula for all numbers.

Step1:

LCM(978, 796) = 389244

GCD(978, 796) = ( 978 x 796 ) / 389244

= 978 / 796

= 978

Step2:

LCM(2, 187) = 374

GCD(2, 187) = ( 2 x 187 ) / 374

= 2 / 187

= 2

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 978, 796, 187, 921 is 1
