Given numbers are 257, 656, 413, 979

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

Apply this formula for all numbers.

Step1:

LCM(257, 656) = 168592

GCD(257, 656) = ( 257 x 656 ) / 168592

= 257 / 656

= 257

Step2:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 257, 656, 413, 979 is 1
