Given numbers are 105, 121, 979, 993
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 121) = 12705
GCD(105, 121) = ( 105 x 121 ) / 12705
= 105 / 121
= 105
Step2:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
Step3:
LCM(1, 993) = 993
GCD(1, 993) = ( 1 x 993 ) / 993
= 1 / 993
= 1
So, Greatest Common Divisor of 105, 121, 979, 993 is 1
