Given numbers are 822, 253, 405, 774

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 253 are 11 x 23

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

Prime factors of 774 are 2 x 3 x 3 x 43

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

Given numbers are 822, 253, 405, 774

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

Apply this formula for all numbers.

Step1:

LCM(822, 253) = 207966

GCD(822, 253) = ( 822 x 253 ) / 207966

= 822 / 253

= 822

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 822, 253, 405, 774 is 1
