Given numbers are 938, 197, 961, 990

The list of prime factors of all numbers are

Prime factors of 938 are 2 x 7 x 67

Prime factors of 197 are 197

Prime factors of 961 are 31 x 31

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 938, 197, 961, 990

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

Apply this formula for all numbers.

Step1:

LCM(938, 197) = 184786

GCD(938, 197) = ( 938 x 197 ) / 184786

= 938 / 197

= 938

Step2:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 938, 197, 961, 990 is 1
