GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(281, 309) = 86829
GCD(281, 309) = ( 281 x 309 ) / 86829
= 281 / 309
= 281
Step2:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 281, 309, 903, 156 is 1
