Given numbers are 828, 656, 404, 245

The list of prime factors of all numbers are

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 404 are 2 x 2 x 101

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 828, 656, 404, 245

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

Apply this formula for all numbers.

Step1:

LCM(828, 656) = 135792

GCD(828, 656) = ( 828 x 656 ) / 135792

= 828 / 656

= 828

Step2:

LCM(4, 404) = 404

GCD(4, 404) = ( 4 x 404 ) / 404

= 4 / 404

= 4

Step3:

LCM(4, 245) = 980

GCD(4, 245) = ( 4 x 245 ) / 980

= 4 / 245

= 4

So, Greatest Common Divisor of 828, 656, 404, 245 is 1
