Given numbers are 390, 868, 116, 291

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 116 are 2 x 2 x 29

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 390, 868, 116, 291

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

Apply this formula for all numbers.

Step1:

LCM(390, 868) = 169260

GCD(390, 868) = ( 390 x 868 ) / 169260

= 390 / 868

= 390

Step2:

LCM(2, 116) = 116

GCD(2, 116) = ( 2 x 116 ) / 116

= 2 / 116

= 2

Step3:

LCM(2, 291) = 582

GCD(2, 291) = ( 2 x 291 ) / 582

= 2 / 291

= 2

So, Greatest Common Divisor of 390, 868, 116, 291 is 1
