Given numbers are 860, 205, 172, 389

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

Apply this formula for all numbers.

Step1:

LCM(860, 205) = 35260

GCD(860, 205) = ( 860 x 205 ) / 35260

= 860 / 205

= 860

Step2:

LCM(5, 172) = 860

GCD(5, 172) = ( 5 x 172 ) / 860

= 5 / 172

= 5

Step3:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

So, Greatest Common Divisor of 860, 205, 172, 389 is 1
