Given numbers are 263, 678, 649, 808

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

Apply this formula for all numbers.

Step1:

LCM(263, 678) = 178314

GCD(263, 678) = ( 263 x 678 ) / 178314

= 263 / 678

= 263

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 263, 678, 649, 808 is 1
