Given numbers are 409, 258, 257, 959

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

Apply this formula for all numbers.

Step1:

LCM(409, 258) = 105522

GCD(409, 258) = ( 409 x 258 ) / 105522

= 409 / 258

= 409

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 959) = 959

GCD(1, 959) = ( 1 x 959 ) / 959

= 1 / 959

= 1

So, Greatest Common Divisor of 409, 258, 257, 959 is 1
