Given numbers are 297, 342, 821, 287

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

Apply this formula for all numbers.

Step1:

LCM(297, 342) = 11286

GCD(297, 342) = ( 297 x 342 ) / 11286

= 297 / 342

= 297

Step2:

LCM(9, 821) = 7389

GCD(9, 821) = ( 9 x 821 ) / 7389

= 9 / 821

= 9

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 297, 342, 821, 287 is 1
