Given numbers are 811, 162, 638, 825

The list of prime factors of all numbers are

Prime factors of 811 are 811

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 638 are 2 x 11 x 29

Prime factors of 825 are 3 x 5 x 5 x 11

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

Given numbers are 811, 162, 638, 825

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

Apply this formula for all numbers.

Step1:

LCM(811, 162) = 131382

GCD(811, 162) = ( 811 x 162 ) / 131382

= 811 / 162

= 811

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

So, Greatest Common Divisor of 811, 162, 638, 825 is 1
