Given numbers are 680, 449, 412, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 449) = 305320
GCD(680, 449) = ( 680 x 449 ) / 305320
= 680 / 449
= 680
Step2:
LCM(1, 412) = 412
GCD(1, 412) = ( 1 x 412 ) / 412
= 1 / 412
= 1
Step3:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
So, Greatest Common Divisor of 680, 449, 412, 605 is 1
