Given numbers are 705, 980, 990, 191

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Prime factors of 191 are 191

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

Given numbers are 705, 980, 990, 191

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

Apply this formula for all numbers.

Step1:

LCM(705, 980) = 138180

GCD(705, 980) = ( 705 x 980 ) / 138180

= 705 / 980

= 705

Step2:

LCM(5, 990) = 990

GCD(5, 990) = ( 5 x 990 ) / 990

= 5 / 990

= 5

Step3:

LCM(5, 191) = 955

GCD(5, 191) = ( 5 x 191 ) / 955

= 5 / 191

= 5

So, Greatest Common Divisor of 705, 980, 990, 191 is 1
