Given numbers are 656, 421, 295, 165

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

Apply this formula for all numbers.

Step1:

LCM(656, 421) = 276176

GCD(656, 421) = ( 656 x 421 ) / 276176

= 656 / 421

= 656

Step2:

LCM(1, 295) = 295

GCD(1, 295) = ( 1 x 295 ) / 295

= 1 / 295

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 656, 421, 295, 165 is 1
