Given numbers are 305, 789, 163, 730
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 789) = 240645
GCD(305, 789) = ( 305 x 789 ) / 240645
= 305 / 789
= 305
Step2:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
Step3:
LCM(1, 730) = 730
GCD(1, 730) = ( 1 x 730 ) / 730
= 1 / 730
= 1
So, Greatest Common Divisor of 305, 789, 163, 730 is 1
