GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 389) = 87525
GCD(225, 389) = ( 225 x 389 ) / 87525
= 225 / 389
= 225
Step2:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 225, 389, 903, 770 is 1
