Given numbers are 797, 470, 253, 420

The list of prime factors of all numbers are

Prime factors of 797 are 797

Prime factors of 470 are 2 x 5 x 47

Prime factors of 253 are 11 x 23

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 797, 470, 253, 420

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

Apply this formula for all numbers.

Step1:

LCM(797, 470) = 374590

GCD(797, 470) = ( 797 x 470 ) / 374590

= 797 / 470

= 797

Step2:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 797, 470, 253, 420 is 1
