GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 388) = 65184
GCD(672, 388) = ( 672 x 388 ) / 65184
= 672 / 388
= 672
Step2:
LCM(4, 497) = 1988
GCD(4, 497) = ( 4 x 497 ) / 1988
= 4 / 497
= 4
Step3:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
So, Greatest Common Divisor of 672, 388, 497, 871 is 1
