Given numbers are 660, 393, 998, 311
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 393) = 86460
GCD(660, 393) = ( 660 x 393 ) / 86460
= 660 / 393
= 660
Step2:
LCM(3, 998) = 2994
GCD(3, 998) = ( 3 x 998 ) / 2994
= 3 / 998
= 3
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 660, 393, 998, 311 is 1
