Given numbers are 173, 665, 763, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(173, 665) = 115045
GCD(173, 665) = ( 173 x 665 ) / 115045
= 173 / 665
= 173
Step2:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 173, 665, 763, 991 is 1
