GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 712) = 610184
GCD(857, 712) = ( 857 x 712 ) / 610184
= 857 / 712
= 857
Step2:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
Step3:
LCM(1, 823) = 823
GCD(1, 823) = ( 1 x 823 ) / 823
= 1 / 823
= 1
So, Greatest Common Divisor of 857, 712, 831, 823 is 1
