Given numbers are 298, 138, 806, 631

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

Apply this formula for all numbers.

Step1:

LCM(298, 138) = 20562

GCD(298, 138) = ( 298 x 138 ) / 20562

= 298 / 138

= 298

Step2:

LCM(2, 806) = 806

GCD(2, 806) = ( 2 x 806 ) / 806

= 2 / 806

= 2

Step3:

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

= 2 / 631

= 2

So, Greatest Common Divisor of 298, 138, 806, 631 is 1
