Given numbers are 905, 225, 389, 553
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 225) = 40725
GCD(905, 225) = ( 905 x 225 ) / 40725
= 905 / 225
= 905
Step2:
LCM(5, 389) = 1945
GCD(5, 389) = ( 5 x 389 ) / 1945
= 5 / 389
= 5
Step3:
LCM(1, 553) = 553
GCD(1, 553) = ( 1 x 553 ) / 553
= 1 / 553
= 1
So, Greatest Common Divisor of 905, 225, 389, 553 is 1
