Given numbers are 623, 890, 223, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 890) = 6230
GCD(623, 890) = ( 623 x 890 ) / 6230
= 623 / 890
= 623
Step2:
LCM(89, 223) = 19847
GCD(89, 223) = ( 89 x 223 ) / 19847
= 89 / 223
= 89
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 623, 890, 223, 309 is 1
