Given numbers are 248, 861, 760, 391

The list of prime factors of all numbers are

Prime factors of 248 are 2 x 2 x 2 x 31

Prime factors of 861 are 3 x 7 x 41

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 391 are 17 x 23

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

Given numbers are 248, 861, 760, 391

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

Apply this formula for all numbers.

Step1:

LCM(248, 861) = 213528

GCD(248, 861) = ( 248 x 861 ) / 213528

= 248 / 861

= 248

Step2:

LCM(1, 760) = 760

GCD(1, 760) = ( 1 x 760 ) / 760

= 1 / 760

= 1

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 248, 861, 760, 391 is 1
