GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 725) = 76850
GCD(530, 725) = ( 530 x 725 ) / 76850
= 530 / 725
= 530
Step2:
LCM(5, 949) = 4745
GCD(5, 949) = ( 5 x 949 ) / 4745
= 5 / 949
= 5
Step3:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
So, Greatest Common Divisor of 530, 725, 949, 172 is 1
