Given numbers are 779, 143, 387, 671
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(779, 143) = 111397
GCD(779, 143) = ( 779 x 143 ) / 111397
= 779 / 143
= 779
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
So, Greatest Common Divisor of 779, 143, 387, 671 is 1
