Given numbers are 188, 242, 392, 251

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

Apply this formula for all numbers.

Step1:

LCM(188, 242) = 22748

GCD(188, 242) = ( 188 x 242 ) / 22748

= 188 / 242

= 188

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

Step3:

LCM(2, 251) = 502

GCD(2, 251) = ( 2 x 251 ) / 502

= 2 / 251

= 2

So, Greatest Common Divisor of 188, 242, 392, 251 is 1
