Given numbers are 663, 169, 411, 320

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

Apply this formula for all numbers.

Step1:

LCM(663, 169) = 8619

GCD(663, 169) = ( 663 x 169 ) / 8619

= 663 / 169

= 663

Step2:

LCM(13, 411) = 5343

GCD(13, 411) = ( 13 x 411 ) / 5343

= 13 / 411

= 13

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 663, 169, 411, 320 is 1
