Given numbers are 449, 122, 720, 325
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(449, 122) = 54778
GCD(449, 122) = ( 449 x 122 ) / 54778
= 449 / 122
= 449
Step2:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
Step3:
LCM(1, 325) = 325
GCD(1, 325) = ( 1 x 325 ) / 325
= 1 / 325
= 1
So, Greatest Common Divisor of 449, 122, 720, 325 is 1
