GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 903) = 168861
GCD(561, 903) = ( 561 x 903 ) / 168861
= 561 / 903
= 561
Step2:
LCM(3, 870) = 870
GCD(3, 870) = ( 3 x 870 ) / 870
= 3 / 870
= 3
Step3:
LCM(3, 199) = 597
GCD(3, 199) = ( 3 x 199 ) / 597
= 3 / 199
= 3
So, Greatest Common Divisor of 561, 903, 870, 199 is 1
