Given numbers are 161, 720, 981, 734
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 720) = 115920
GCD(161, 720) = ( 161 x 720 ) / 115920
= 161 / 720
= 161
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 734) = 734
GCD(1, 734) = ( 1 x 734 ) / 734
= 1 / 734
= 1
So, Greatest Common Divisor of 161, 720, 981, 734 is 1
