Given numbers are 789, 631, 245, 979
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 631) = 497859
GCD(789, 631) = ( 789 x 631 ) / 497859
= 789 / 631
= 789
Step2:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
Step3:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
So, Greatest Common Divisor of 789, 631, 245, 979 is 1
