Given numbers are 398, 778, 201, 608

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 778 are 2 x 389

Prime factors of 201 are 3 x 67

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

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

Given numbers are 398, 778, 201, 608

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

Apply this formula for all numbers.

Step1:

LCM(398, 778) = 154822

GCD(398, 778) = ( 398 x 778 ) / 154822

= 398 / 778

= 398

Step2:

LCM(2, 201) = 402

GCD(2, 201) = ( 2 x 201 ) / 402

= 2 / 201

= 2

Step3:

LCM(1, 608) = 608

GCD(1, 608) = ( 1 x 608 ) / 608

= 1 / 608

= 1

So, Greatest Common Divisor of 398, 778, 201, 608 is 1
