Given numbers are 561, 130, 743, 203

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 130 are 2 x 5 x 13

Prime factors of 743 are 743

Prime factors of 203 are 7 x 29

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

Given numbers are 561, 130, 743, 203

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

Apply this formula for all numbers.

Step1:

LCM(561, 130) = 72930

GCD(561, 130) = ( 561 x 130 ) / 72930

= 561 / 130

= 561

Step2:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 561, 130, 743, 203 is 1
