Given numbers are 831, 711, 123, 165

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(831, 711) = 196947

GCD(831, 711) = ( 831 x 711 ) / 196947

= 831 / 711

= 831

Step2:

LCM(3, 123) = 123

GCD(3, 123) = ( 3 x 123 ) / 123

= 3 / 123

= 3

Step3:

LCM(3, 165) = 165

GCD(3, 165) = ( 3 x 165 ) / 165

= 3 / 165

= 3

So, Greatest Common Divisor of 831, 711, 123, 165 is 3
