Given numbers are 203, 827, 644, 871
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(203, 827) = 167881
GCD(203, 827) = ( 203 x 827 ) / 167881
= 203 / 827
= 203
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
So, Greatest Common Divisor of 203, 827, 644, 871 is 1
