Given numbers are 991, 386, 832, 421

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

Apply this formula for all numbers.

Step1:

LCM(991, 386) = 382526

GCD(991, 386) = ( 991 x 386 ) / 382526

= 991 / 386

= 991

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 991, 386, 832, 421 is 1
