Given numbers are 121, 921, 189

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

Apply this formula for all numbers.

Step1:

LCM(121, 921) = 111441

GCD(121, 921) = ( 121 x 921 ) / 111441

= 121 / 921

= 121

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 121, 921, 189 is 1
