Given numbers are 728, 838, 544, 665

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 838 are 2 x 419

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 728, 838, 544, 665

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

Apply this formula for all numbers.

Step1:

LCM(728, 838) = 305032

GCD(728, 838) = ( 728 x 838 ) / 305032

= 728 / 838

= 728

Step2:

LCM(2, 544) = 544

GCD(2, 544) = ( 2 x 544 ) / 544

= 2 / 544

= 2

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 728, 838, 544, 665 is 1
