Given numbers are 311, 420, 978, 291

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 978 are 2 x 3 x 163

Prime factors of 291 are 3 x 97

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

Given numbers are 311, 420, 978, 291

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

Apply this formula for all numbers.

Step1:

LCM(311, 420) = 130620

GCD(311, 420) = ( 311 x 420 ) / 130620

= 311 / 420

= 311

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 311, 420, 978, 291 is 1
