GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 288) = 1152
GCD(128, 288) = ( 128 x 288 ) / 1152
= 128 / 288
= 128
Step2:
LCM(32, 815) = 26080
GCD(32, 815) = ( 32 x 815 ) / 26080
= 32 / 815
= 32
So, Greatest Common Divisor of 128, 288, 815 is 1
