Given numbers are 728, 350, 777, 638

The list of prime factors of all numbers are

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

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 777 are 3 x 7 x 37

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 728, 350, 777, 638

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

Apply this formula for all numbers.

Step1:

LCM(728, 350) = 18200

GCD(728, 350) = ( 728 x 350 ) / 18200

= 728 / 350

= 728

Step2:

LCM(14, 777) = 1554

GCD(14, 777) = ( 14 x 777 ) / 1554

= 14 / 777

= 14

Step3:

LCM(7, 638) = 4466

GCD(7, 638) = ( 7 x 638 ) / 4466

= 7 / 638

= 7

So, Greatest Common Divisor of 728, 350, 777, 638 is 1
