Given numbers are 247, 156, 484, 897

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 897 are 3 x 13 x 23

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

Given numbers are 247, 156, 484, 897

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

Apply this formula for all numbers.

Step1:

LCM(247, 156) = 2964

GCD(247, 156) = ( 247 x 156 ) / 2964

= 247 / 156

= 247

Step2:

LCM(13, 484) = 6292

GCD(13, 484) = ( 13 x 484 ) / 6292

= 13 / 484

= 13

Step3:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

So, Greatest Common Divisor of 247, 156, 484, 897 is 1
