Given numbers are 711, 905, 830, 812

The list of prime factors of all numbers are

Prime factors of 711 are 3 x 3 x 79

Prime factors of 905 are 5 x 181

Prime factors of 830 are 2 x 5 x 83

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

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

Given numbers are 711, 905, 830, 812

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

Apply this formula for all numbers.

Step1:

LCM(711, 905) = 643455

GCD(711, 905) = ( 711 x 905 ) / 643455

= 711 / 905

= 711

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 711, 905, 830, 812 is 1
