Given numbers are 828, 408, 281, 561

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 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 281 are 281

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, 408, 281, 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, 408) = 28152

GCD(828, 408) = ( 828 x 408 ) / 28152

= 828 / 408

= 828

Step2:

LCM(12, 281) = 3372

GCD(12, 281) = ( 12 x 281 ) / 3372

= 12 / 281

= 12

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 828, 408, 281, 561 is 1
