Given numbers are 423, 787, 858, 320

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 787 are 787

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 423, 787, 858, 320

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

Apply this formula for all numbers.

Step1:

LCM(423, 787) = 332901

GCD(423, 787) = ( 423 x 787 ) / 332901

= 423 / 787

= 423

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 423, 787, 858, 320 is 1
