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 988 are 2 x 2 x 13 x 19

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 828, 988, 156, 561

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

Apply this formula for all numbers.

Step1:

LCM(828, 988) = 204516

GCD(828, 988) = ( 828 x 988 ) / 204516

= 828 / 988

= 828

Step2:

LCM(4, 156) = 156

GCD(4, 156) = ( 4 x 156 ) / 156

= 4 / 156

= 4

Step3:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

So, Greatest Common Divisor of 828, 988, 156, 561 is 1
