Given numbers are 251, 488, 641, 409

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

Apply this formula for all numbers.

Step1:

LCM(251, 488) = 122488

GCD(251, 488) = ( 251 x 488 ) / 122488

= 251 / 488

= 251

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 251, 488, 641, 409 is 1
