Given numbers are 285, 665, 672, 871
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 665) = 1995
GCD(285, 665) = ( 285 x 665 ) / 1995
= 285 / 665
= 285
Step2:
LCM(95, 672) = 63840
GCD(95, 672) = ( 95 x 672 ) / 63840
= 95 / 672
= 95
Step3:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
So, Greatest Common Divisor of 285, 665, 672, 871 is 1
