Given numbers are 691, 980, 969, 477

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

Apply this formula for all numbers.

Step1:

LCM(691, 980) = 677180

GCD(691, 980) = ( 691 x 980 ) / 677180

= 691 / 980

= 691

Step2:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

Step3:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

So, Greatest Common Divisor of 691, 980, 969, 477 is 1
