Given numbers are 291, 557, 290, 768

The list of prime factors of all numbers are

Prime factors of 291 are 3 x 97

Prime factors of 557 are 557

Prime factors of 290 are 2 x 5 x 29

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 291, 557, 290, 768

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

Apply this formula for all numbers.

Step1:

LCM(291, 557) = 162087

GCD(291, 557) = ( 291 x 557 ) / 162087

= 291 / 557

= 291

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 291, 557, 290, 768 is 1
