Given numbers are 203, 349, 657, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(203, 349) = 70847
GCD(203, 349) = ( 203 x 349 ) / 70847
= 203 / 349
= 203
Step2:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
Step3:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
So, Greatest Common Divisor of 203, 349, 657, 985 is 1
