Given numbers are 188, 678, 221, 266

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

Apply this formula for all numbers.

Step1:

LCM(188, 678) = 63732

GCD(188, 678) = ( 188 x 678 ) / 63732

= 188 / 678

= 188

Step2:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

Step3:

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

= 1 / 266

= 1

So, Greatest Common Divisor of 188, 678, 221, 266 is 1
