Given numbers are 280, 389, 181

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

Apply this formula for all numbers.

Step1:

LCM(280, 389) = 108920

GCD(280, 389) = ( 280 x 389 ) / 108920

= 280 / 389

= 280

Step2:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 280, 389, 181 is 1
