Given numbers are 979, 689, 401, 676
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(979, 689) = 674531
GCD(979, 689) = ( 979 x 689 ) / 674531
= 979 / 689
= 979
Step2:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
Step3:
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
= 1 / 676
= 1
So, Greatest Common Divisor of 979, 689, 401, 676 is 1
