Given numbers are 398, 728, 850, 565

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

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

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 565 are 5 x 113

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

Given numbers are 398, 728, 850, 565

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

Apply this formula for all numbers.

Step1:

LCM(398, 728) = 144872

GCD(398, 728) = ( 398 x 728 ) / 144872

= 398 / 728

= 398

Step2:

LCM(2, 850) = 850

GCD(2, 850) = ( 2 x 850 ) / 850

= 2 / 850

= 2

Step3:

LCM(2, 565) = 1130

GCD(2, 565) = ( 2 x 565 ) / 1130

= 2 / 565

= 2

So, Greatest Common Divisor of 398, 728, 850, 565 is 1
