GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 171) = 154755
GCD(905, 171) = ( 905 x 171 ) / 154755
= 905 / 171
= 905
Step2:
LCM(1, 872) = 872
GCD(1, 872) = ( 1 x 872 ) / 872
= 1 / 872
= 1
Step3:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
So, Greatest Common Divisor of 905, 171, 872, 885 is 1
