Given numbers are 217, 792, 221, 280

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 221 are 13 x 17

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 217, 792, 221, 280

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

Apply this formula for all numbers.

Step1:

LCM(217, 792) = 171864

GCD(217, 792) = ( 217 x 792 ) / 171864

= 217 / 792

= 217

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 217, 792, 221, 280 is 1
