Given numbers are 871, 668, 122, 291

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

Apply this formula for all numbers.

Step1:

LCM(871, 668) = 581828

GCD(871, 668) = ( 871 x 668 ) / 581828

= 871 / 668

= 871

Step2:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 871, 668, 122, 291 is 1
