Given numbers are 502, 721, 209, 871
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(502, 721) = 361942
GCD(502, 721) = ( 502 x 721 ) / 361942
= 502 / 721
= 502
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
So, Greatest Common Divisor of 502, 721, 209, 871 is 1
