Given numbers are 729, 305, 174, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 305) = 222345
GCD(729, 305) = ( 729 x 305 ) / 222345
= 729 / 305
= 729
Step2:
LCM(1, 174) = 174
GCD(1, 174) = ( 1 x 174 ) / 174
= 1 / 174
= 1
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 729, 305, 174, 435 is 1
