Given numbers are 128, 418, 440, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 418) = 26752
GCD(128, 418) = ( 128 x 418 ) / 26752
= 128 / 418
= 128
Step2:
LCM(2, 440) = 440
GCD(2, 440) = ( 2 x 440 ) / 440
= 2 / 440
= 2
Step3:
LCM(2, 181) = 362
GCD(2, 181) = ( 2 x 181 ) / 362
= 2 / 181
= 2
So, Greatest Common Divisor of 128, 418, 440, 181 is 1
