Given numbers are 660, 912, 979, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 912) = 50160
GCD(660, 912) = ( 660 x 912 ) / 50160
= 660 / 912
= 660
Step2:
LCM(12, 979) = 11748
GCD(12, 979) = ( 12 x 979 ) / 11748
= 12 / 979
= 12
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 660, 912, 979, 989 is 1
