Given numbers are 897, 257, 962, 420

The list of prime factors of all numbers are

Prime factors of 897 are 3 x 13 x 23

Prime factors of 257 are 257

Prime factors of 962 are 2 x 13 x 37

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 897, 257, 962, 420

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

Apply this formula for all numbers.

Step1:

LCM(897, 257) = 230529

GCD(897, 257) = ( 897 x 257 ) / 230529

= 897 / 257

= 897

Step2:

LCM(1, 962) = 962

GCD(1, 962) = ( 1 x 962 ) / 962

= 1 / 962

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 897, 257, 962, 420 is 1
