Given numbers are 291, 130, 285, 721

The list of prime factors of all numbers are

Prime factors of 291 are 3 x 97

Prime factors of 130 are 2 x 5 x 13

Prime factors of 285 are 3 x 5 x 19

Prime factors of 721 are 7 x 103

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

Given numbers are 291, 130, 285, 721

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

Apply this formula for all numbers.

Step1:

LCM(291, 130) = 37830

GCD(291, 130) = ( 291 x 130 ) / 37830

= 291 / 130

= 291

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 291, 130, 285, 721 is 1
