GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 421) = 360797
GCD(857, 421) = ( 857 x 421 ) / 360797
= 857 / 421
= 857
Step2:
LCM(1, 976) = 976
GCD(1, 976) = ( 1 x 976 ) / 976
= 1 / 976
= 1
Step3:
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
= 1 / 849
= 1
So, Greatest Common Divisor of 857, 421, 976, 849 is 1
