Given numbers are 154, 209, 630, 791

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 209 are 11 x 19

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 791 are 7 x 113

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

Given numbers are 154, 209, 630, 791

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

Apply this formula for all numbers.

Step1:

LCM(154, 209) = 2926

GCD(154, 209) = ( 154 x 209 ) / 2926

= 154 / 209

= 154

Step2:

LCM(11, 630) = 6930

GCD(11, 630) = ( 11 x 630 ) / 6930

= 11 / 630

= 11

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 154, 209, 630, 791 is 1
