Given numbers are 518, 209, 161

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

Apply this formula for all numbers.

Step1:

LCM(518, 209) = 108262

GCD(518, 209) = ( 518 x 209 ) / 108262

= 518 / 209

= 518

Step2:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 518, 209, 161 is 1
