Given numbers are 731, 897, 420, 771

The list of prime factors of all numbers are

Prime factors of 731 are 17 x 43

Prime factors of 897 are 3 x 13 x 23

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

Prime factors of 771 are 3 x 257

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

Given numbers are 731, 897, 420, 771

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

Apply this formula for all numbers.

Step1:

LCM(731, 897) = 655707

GCD(731, 897) = ( 731 x 897 ) / 655707

= 731 / 897

= 731

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 731, 897, 420, 771 is 1
