Given numbers are 210, 390, 108, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 390) = 2730
GCD(210, 390) = ( 210 x 390 ) / 2730
= 210 / 390
= 210
Step2:
LCM(30, 108) = 540
GCD(30, 108) = ( 30 x 108 ) / 540
= 30 / 108
= 30
Step3:
LCM(6, 231) = 462
GCD(6, 231) = ( 6 x 231 ) / 462
= 6 / 231
= 6
So, Greatest Common Divisor of 210, 390, 108, 231 is 3
