Given numbers are 257, 615, 409, 563

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

Apply this formula for all numbers.

Step1:

LCM(257, 615) = 158055

GCD(257, 615) = ( 257 x 615 ) / 158055

= 257 / 615

= 257

Step2:

LCM(1, 409) = 409

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

= 1 / 409

= 1

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 257, 615, 409, 563 is 1
