GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 459) = 99603
GCD(217, 459) = ( 217 x 459 ) / 99603
= 217 / 459
= 217
Step2:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
Step3:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 217, 459, 440, 124 is 1
