Given numbers are 871, 585, 965, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 585) = 39195
GCD(871, 585) = ( 871 x 585 ) / 39195
= 871 / 585
= 871
Step2:
LCM(13, 965) = 12545
GCD(13, 965) = ( 13 x 965 ) / 12545
= 13 / 965
= 13
Step3:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
So, Greatest Common Divisor of 871, 585, 965, 808 is 1
