Given numbers are 871, 879, 422, 666
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 879) = 765609
GCD(871, 879) = ( 871 x 879 ) / 765609
= 871 / 879
= 871
Step2:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
Step3:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
So, Greatest Common Divisor of 871, 879, 422, 666 is 1
