GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 921) = 69075
GCD(225, 921) = ( 225 x 921 ) / 69075
= 225 / 921
= 225
Step2:
LCM(3, 685) = 2055
GCD(3, 685) = ( 3 x 685 ) / 2055
= 3 / 685
= 3
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 225, 921, 685, 656 is 1
