Given numbers are 155, 487, 257, 565

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

Apply this formula for all numbers.

Step1:

LCM(155, 487) = 75485

GCD(155, 487) = ( 155 x 487 ) / 75485

= 155 / 487

= 155

Step2:

LCM(1, 257) = 257

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

= 1 / 257

= 1

Step3:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

So, Greatest Common Divisor of 155, 487, 257, 565 is 1
