Given numbers are 663, 299, 661, 278

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

Apply this formula for all numbers.

Step1:

LCM(663, 299) = 15249

GCD(663, 299) = ( 663 x 299 ) / 15249

= 663 / 299

= 663

Step2:

LCM(13, 661) = 8593

GCD(13, 661) = ( 13 x 661 ) / 8593

= 13 / 661

= 13

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 663, 299, 661, 278 is 1
