Given numbers are 964, 990, 391, 193

The list of prime factors of all numbers are

Prime factors of 964 are 2 x 2 x 241

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

Prime factors of 391 are 17 x 23

Prime factors of 193 are 193

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

Given numbers are 964, 990, 391, 193

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

Apply this formula for all numbers.

Step1:

LCM(964, 990) = 477180

GCD(964, 990) = ( 964 x 990 ) / 477180

= 964 / 990

= 964

Step2:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

Step3:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

So, Greatest Common Divisor of 964, 990, 391, 193 is 1
