GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 891) = 16929
GCD(209, 891) = ( 209 x 891 ) / 16929
= 209 / 891
= 209
Step2:
LCM(11, 903) = 9933
GCD(11, 903) = ( 11 x 903 ) / 9933
= 11 / 903
= 11
Step3:
LCM(1, 559) = 559
GCD(1, 559) = ( 1 x 559 ) / 559
= 1 / 559
= 1
So, Greatest Common Divisor of 209, 891, 903, 559 is 1
