Given numbers are 238, 688, 811, 998

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

Apply this formula for all numbers.

Step1:

LCM(238, 688) = 81872

GCD(238, 688) = ( 238 x 688 ) / 81872

= 238 / 688

= 238

Step2:

LCM(2, 811) = 1622

GCD(2, 811) = ( 2 x 811 ) / 1622

= 2 / 811

= 2

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 238, 688, 811, 998 is 1
