Given numbers are 225, 695, 388, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 695) = 31275
GCD(225, 695) = ( 225 x 695 ) / 31275
= 225 / 695
= 225
Step2:
LCM(5, 388) = 1940
GCD(5, 388) = ( 5 x 388 ) / 1940
= 5 / 388
= 5
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 225, 695, 388, 645 is 1
