Given numbers are 823, 764, 648, 426

The list of prime factors of all numbers are

Prime factors of 823 are 823

Prime factors of 764 are 2 x 2 x 191

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 823, 764, 648, 426

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

Apply this formula for all numbers.

Step1:

LCM(823, 764) = 628772

GCD(823, 764) = ( 823 x 764 ) / 628772

= 823 / 764

= 823

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 823, 764, 648, 426 is 1
