Given numbers are 663, 138, 483, 238

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

Apply this formula for all numbers.

Step1:

LCM(663, 138) = 30498

GCD(663, 138) = ( 663 x 138 ) / 30498

= 663 / 138

= 663

Step2:

LCM(3, 483) = 483

GCD(3, 483) = ( 3 x 483 ) / 483

= 3 / 483

= 3

Step3:

LCM(3, 238) = 714

GCD(3, 238) = ( 3 x 238 ) / 714

= 3 / 238

= 3

So, Greatest Common Divisor of 663, 138, 483, 238 is 1
