Given numbers are 773, 728, 648, 445

The list of prime factors of all numbers are

Prime factors of 773 are 773

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 445 are 5 x 89

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

Given numbers are 773, 728, 648, 445

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

Apply this formula for all numbers.

Step1:

LCM(773, 728) = 562744

GCD(773, 728) = ( 773 x 728 ) / 562744

= 773 / 728

= 773

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 773, 728, 648, 445 is 1
