Given numbers are 827, 129, 871, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(827, 129) = 106683
GCD(827, 129) = ( 827 x 129 ) / 106683
= 827 / 129
= 827
Step2:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 827, 129, 871, 649 is 1
