GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(979, 686) = 671594
GCD(979, 686) = ( 979 x 686 ) / 671594
= 979 / 686
= 979
Step2:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 979, 686, 423, 845 is 1
