Given numbers are 826, 405, 990, 215

The list of prime factors of all numbers are

Prime factors of 826 are 2 x 7 x 59

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

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 215 are 5 x 43

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

Given numbers are 826, 405, 990, 215

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

Apply this formula for all numbers.

Step1:

LCM(826, 405) = 334530

GCD(826, 405) = ( 826 x 405 ) / 334530

= 826 / 405

= 826

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 826, 405, 990, 215 is 1
