Given numbers are 163, 261, 255, 615

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

Apply this formula for all numbers.

Step1:

LCM(163, 261) = 42543

GCD(163, 261) = ( 163 x 261 ) / 42543

= 163 / 261

= 163

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 163, 261, 255, 615 is 1
