GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 915) = 253455
GCD(831, 915) = ( 831 x 915 ) / 253455
= 831 / 915
= 831
Step2:
LCM(3, 225) = 225
GCD(3, 225) = ( 3 x 225 ) / 225
= 3 / 225
= 3
Step3:
LCM(3, 177) = 177
GCD(3, 177) = ( 3 x 177 ) / 177
= 3 / 177
= 3
So, Greatest Common Divisor of 831, 915, 225, 177 is 3
