GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 129) = 9675
GCD(225, 129) = ( 225 x 129 ) / 9675
= 225 / 129
= 225
Step2:
LCM(3, 747) = 747
GCD(3, 747) = ( 3 x 747 ) / 747
= 3 / 747
= 3
Step3:
LCM(3, 997) = 2991
GCD(3, 997) = ( 3 x 997 ) / 2991
= 3 / 997
= 3
So, Greatest Common Divisor of 225, 129, 747, 997 is 1
