Given numbers are 680, 561, 403, 518
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 561) = 22440
GCD(680, 561) = ( 680 x 561 ) / 22440
= 680 / 561
= 680
Step2:
LCM(17, 403) = 6851
GCD(17, 403) = ( 17 x 403 ) / 6851
= 17 / 403
= 17
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 680, 561, 403, 518 is 1
