Given numbers are 691, 860, 261

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

Apply this formula for all numbers.

Step1:

LCM(691, 860) = 594260

GCD(691, 860) = ( 691 x 860 ) / 594260

= 691 / 860

= 691

Step2:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 691, 860, 261 is 1
