GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(725, 905) = 131225
GCD(725, 905) = ( 725 x 905 ) / 131225
= 725 / 905
= 725
Step2:
LCM(5, 120) = 120
GCD(5, 120) = ( 5 x 120 ) / 120
= 5 / 120
= 5
Step3:
LCM(5, 385) = 385
GCD(5, 385) = ( 5 x 385 ) / 385
= 5 / 385
= 5
So, Greatest Common Divisor of 725, 905, 120, 385 is 5
