Given numbers are 828, 348, 249, 644

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 348 are 2 x 2 x 3 x 29

Prime factors of 249 are 3 x 83

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 828, 348, 249, 644

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

Apply this formula for all numbers.

Step1:

LCM(828, 348) = 24012

GCD(828, 348) = ( 828 x 348 ) / 24012

= 828 / 348

= 828

Step2:

LCM(12, 249) = 996

GCD(12, 249) = ( 12 x 249 ) / 996

= 12 / 249

= 12

Step3:

LCM(3, 644) = 1932

GCD(3, 644) = ( 3 x 644 ) / 1932

= 3 / 644

= 3

So, Greatest Common Divisor of 828, 348, 249, 644 is 1
