Given numbers are 161, 665, 997, 310
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 665) = 15295
GCD(161, 665) = ( 161 x 665 ) / 15295
= 161 / 665
= 161
Step2:
LCM(7, 997) = 6979
GCD(7, 997) = ( 7 x 997 ) / 6979
= 7 / 997
= 7
Step3:
LCM(1, 310) = 310
GCD(1, 310) = ( 1 x 310 ) / 310
= 1 / 310
= 1
So, Greatest Common Divisor of 161, 665, 997, 310 is 1
