Given numbers are 356, 367, 805, 420

The list of prime factors of all numbers are

Prime factors of 356 are 2 x 2 x 89

Prime factors of 367 are 367

Prime factors of 805 are 5 x 7 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 356, 367, 805, 420

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

Apply this formula for all numbers.

Step1:

LCM(356, 367) = 130652

GCD(356, 367) = ( 356 x 367 ) / 130652

= 356 / 367

= 356

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 356, 367, 805, 420 is 1
