Given numbers are 865, 812, 688, 441

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

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

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 441 are 3 x 3 x 7 x 7

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

Given numbers are 865, 812, 688, 441

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

Apply this formula for all numbers.

Step1:

LCM(865, 812) = 702380

GCD(865, 812) = ( 865 x 812 ) / 702380

= 865 / 812

= 865

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

= 1 / 441

= 1

So, Greatest Common Divisor of 865, 812, 688, 441 is 1
