Given numbers are 434, 775, 291, 391

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 775 are 5 x 5 x 31

Prime factors of 291 are 3 x 97

Prime factors of 391 are 17 x 23

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

Given numbers are 434, 775, 291, 391

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

Apply this formula for all numbers.

Step1:

LCM(434, 775) = 10850

GCD(434, 775) = ( 434 x 775 ) / 10850

= 434 / 775

= 434

Step2:

LCM(31, 291) = 9021

GCD(31, 291) = ( 31 x 291 ) / 9021

= 31 / 291

= 31

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 434, 775, 291, 391 is 1
