Given numbers are 812, 856, 561, 414

The list of prime factors of all numbers are

Prime factors of 812 are 2 x 2 x 7 x 29

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

Prime factors of 561 are 3 x 11 x 17

Prime factors of 414 are 2 x 3 x 3 x 23

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

Given numbers are 812, 856, 561, 414

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

Apply this formula for all numbers.

Step1:

LCM(812, 856) = 173768

GCD(812, 856) = ( 812 x 856 ) / 173768

= 812 / 856

= 812

Step2:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

Step3:

LCM(1, 414) = 414

GCD(1, 414) = ( 1 x 414 ) / 414

= 1 / 414

= 1

So, Greatest Common Divisor of 812, 856, 561, 414 is 1
