GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(554, 531) = 294174
GCD(554, 531) = ( 554 x 531 ) / 294174
= 554 / 531
= 554
Step2:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 554, 531, 891, 128 is 1
