Given numbers are 249, 431, 873, 688

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

Apply this formula for all numbers.

Step1:

LCM(249, 431) = 107319

GCD(249, 431) = ( 249 x 431 ) / 107319

= 249 / 431

= 249

Step2:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 249, 431, 873, 688 is 1
