Given numbers are 171, 209, 492, 445

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

Apply this formula for all numbers.

Step1:

LCM(171, 209) = 1881

GCD(171, 209) = ( 171 x 209 ) / 1881

= 171 / 209

= 171

Step2:

LCM(19, 492) = 9348

GCD(19, 492) = ( 19 x 492 ) / 9348

= 19 / 492

= 19

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 171, 209, 492, 445 is 1
