Given numbers are 978, 843, 680

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

Apply this formula for all numbers.

Step1:

LCM(978, 843) = 274818

GCD(978, 843) = ( 978 x 843 ) / 274818

= 978 / 843

= 978

Step2:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

So, Greatest Common Divisor of 978, 843, 680 is 1
