Given numbers are 274, 415, 247, 391

The list of prime factors of all numbers are

Prime factors of 274 are 2 x 137

Prime factors of 415 are 5 x 83

Prime factors of 247 are 13 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 274, 415, 247, 391

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

Apply this formula for all numbers.

Step1:

LCM(274, 415) = 113710

GCD(274, 415) = ( 274 x 415 ) / 113710

= 274 / 415

= 274

Step2:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

Step3:

LCM(1, 391) = 391

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

= 1 / 391

= 1

So, Greatest Common Divisor of 274, 415, 247, 391 is 1
