Given numbers are 297, 649, 263, 805

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

Apply this formula for all numbers.

Step1:

LCM(297, 649) = 17523

GCD(297, 649) = ( 297 x 649 ) / 17523

= 297 / 649

= 297

Step2:

LCM(11, 263) = 2893

GCD(11, 263) = ( 11 x 263 ) / 2893

= 11 / 263

= 11

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 297, 649, 263, 805 is 1
