Given numbers are 871, 900, 212, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 900) = 783900
GCD(871, 900) = ( 871 x 900 ) / 783900
= 871 / 900
= 871
Step2:
LCM(1, 212) = 212
GCD(1, 212) = ( 1 x 212 ) / 212
= 1 / 212
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 871, 900, 212, 815 is 1
