Given numbers are 515, 991, 168, 853
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 991) = 510365
GCD(515, 991) = ( 515 x 991 ) / 510365
= 515 / 991
= 515
Step2:
LCM(1, 168) = 168
GCD(1, 168) = ( 1 x 168 ) / 168
= 1 / 168
= 1
Step3:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
So, Greatest Common Divisor of 515, 991, 168, 853 is 1
