Given numbers are 191, 221, 75

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

Apply this formula for all numbers.

Step1:

LCM(191, 221) = 42211

GCD(191, 221) = ( 191 x 221 ) / 42211

= 191 / 221

= 191

Step2:

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

= 1 / 75

= 1

So, Greatest Common Divisor of 191, 221, 75 is 1
