Given numbers are 729, 665, 445, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 665) = 484785
GCD(729, 665) = ( 729 x 665 ) / 484785
= 729 / 665
= 729
Step2:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 729, 665, 445, 129 is 1
