Given numbers are 171, 412, 613, 505

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

Apply this formula for all numbers.

Step1:

LCM(171, 412) = 70452

GCD(171, 412) = ( 171 x 412 ) / 70452

= 171 / 412

= 171

Step2:

LCM(1, 613) = 613

GCD(1, 613) = ( 1 x 613 ) / 613

= 1 / 613

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 171, 412, 613, 505 is 1
