The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 391, 788, 660, 347

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

Apply this formula for all numbers.

Step1:

LCM(391, 788) = 308108

GCD(391, 788) = ( 391 x 788 ) / 308108

= 391 / 788

= 391

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 391, 788, 660, 347 is 1
