Given numbers are 391, 973, 652, 164

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

Apply this formula for all numbers.

Step1:

LCM(391, 973) = 380443

GCD(391, 973) = ( 391 x 973 ) / 380443

= 391 / 973

= 391

Step2:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

Step3:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

So, Greatest Common Divisor of 391, 973, 652, 164 is 1
