Given numbers are 791, 321, 990, 448

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 321 are 3 x 107

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

Given numbers are 791, 321, 990, 448

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

Apply this formula for all numbers.

Step1:

LCM(791, 321) = 253911

GCD(791, 321) = ( 791 x 321 ) / 253911

= 791 / 321

= 791

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 791, 321, 990, 448 is 1
