Given numbers are 725, 625, 261, 126
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(725, 625) = 18125
GCD(725, 625) = ( 725 x 625 ) / 18125
= 725 / 625
= 725
Step2:
LCM(25, 261) = 6525
GCD(25, 261) = ( 25 x 261 ) / 6525
= 25 / 261
= 25
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 725, 625, 261, 126 is 1
