Given numbers are 856, 532, 390, 843

The list of prime factors of all numbers are

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 532 are 2 x 2 x 7 x 19

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 843 are 3 x 281

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

Given numbers are 856, 532, 390, 843

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

Apply this formula for all numbers.

Step1:

LCM(856, 532) = 113848

GCD(856, 532) = ( 856 x 532 ) / 113848

= 856 / 532

= 856

Step2:

LCM(4, 390) = 780

GCD(4, 390) = ( 4 x 390 ) / 780

= 4 / 390

= 4

Step3:

LCM(2, 843) = 1686

GCD(2, 843) = ( 2 x 843 ) / 1686

= 2 / 843

= 2

So, Greatest Common Divisor of 856, 532, 390, 843 is 1
