GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(725, 165) = 23925
GCD(725, 165) = ( 725 x 165 ) / 23925
= 725 / 165
= 725
Step2:
LCM(5, 381) = 1905
GCD(5, 381) = ( 5 x 381 ) / 1905
= 5 / 381
= 5
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 725, 165, 381, 981 is 1
