Given numbers are 390, 311, 683, 667
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 311) = 121290
GCD(390, 311) = ( 390 x 311 ) / 121290
= 390 / 311
= 390
Step2:
LCM(1, 683) = 683
GCD(1, 683) = ( 1 x 683 ) / 683
= 1 / 683
= 1
Step3:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
So, Greatest Common Divisor of 390, 311, 683, 667 is 1
