Given numbers are 987, 665, 979, 897
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 665) = 93765
GCD(987, 665) = ( 987 x 665 ) / 93765
= 987 / 665
= 987
Step2:
LCM(7, 979) = 6853
GCD(7, 979) = ( 7 x 979 ) / 6853
= 7 / 979
= 7
Step3:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
So, Greatest Common Divisor of 987, 665, 979, 897 is 1
