Given numbers are 231, 285, 629, 663

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

Apply this formula for all numbers.

Step1:

LCM(231, 285) = 21945

GCD(231, 285) = ( 231 x 285 ) / 21945

= 231 / 285

= 231

Step2:

LCM(3, 629) = 1887

GCD(3, 629) = ( 3 x 629 ) / 1887

= 3 / 629

= 3

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 231, 285, 629, 663 is 1
