GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 871) = 668928
GCD(768, 871) = ( 768 x 871 ) / 668928
= 768 / 871
= 768
Step2:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 768, 871, 806, 556 is 1
