Given numbers are 615, 695, 255, 457

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

Apply this formula for all numbers.

Step1:

LCM(615, 695) = 85485

GCD(615, 695) = ( 615 x 695 ) / 85485

= 615 / 695

= 615

Step2:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

Step3:

LCM(5, 457) = 2285

GCD(5, 457) = ( 5 x 457 ) / 2285

= 5 / 457

= 5

So, Greatest Common Divisor of 615, 695, 255, 457 is 1
