Given numbers are 291, 189, 921, 308

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

Apply this formula for all numbers.

Step1:

LCM(291, 189) = 18333

GCD(291, 189) = ( 291 x 189 ) / 18333

= 291 / 189

= 291

Step2:

LCM(3, 921) = 921

GCD(3, 921) = ( 3 x 921 ) / 921

= 3 / 921

= 3

Step3:

LCM(3, 308) = 924

GCD(3, 308) = ( 3 x 308 ) / 924

= 3 / 308

= 3

So, Greatest Common Divisor of 291, 189, 921, 308 is 1
