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

Apply this formula for all numbers.

Step1:

LCM(771, 831) = 213567

GCD(771, 831) = ( 771 x 831 ) / 213567

= 771 / 831

= 771

Step2:

LCM(3, 177) = 177

GCD(3, 177) = ( 3 x 177 ) / 177

= 3 / 177

= 3

Step3:

LCM(3, 225) = 225

GCD(3, 225) = ( 3 x 225 ) / 225

= 3 / 225

= 3

So, Greatest Common Divisor of 771, 831, 177, 225 is 3
