Given numbers are 663, 581, 111, 779
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 581) = 385203
GCD(663, 581) = ( 663 x 581 ) / 385203
= 663 / 581
= 663
Step2:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
Step3:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
So, Greatest Common Divisor of 663, 581, 111, 779 is 1
