GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 981) = 840717
GCD(857, 981) = ( 857 x 981 ) / 840717
= 857 / 981
= 857
Step2:
LCM(1, 839) = 839
GCD(1, 839) = ( 1 x 839 ) / 839
= 1 / 839
= 1
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 857, 981, 839, 209 is 1
