Given numbers are 938, 405, 669, 810

The list of prime factors of all numbers are

Prime factors of 938 are 2 x 7 x 67

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 669 are 3 x 223

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 938, 405, 669, 810

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

Apply this formula for all numbers.

Step1:

LCM(938, 405) = 379890

GCD(938, 405) = ( 938 x 405 ) / 379890

= 938 / 405

= 938

Step2:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 938, 405, 669, 810 is 1
