Given numbers are 806, 260, 138, 477

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 138 are 2 x 3 x 23

Prime factors of 477 are 3 x 3 x 53

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

Given numbers are 806, 260, 138, 477

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

Apply this formula for all numbers.

Step1:

LCM(806, 260) = 8060

GCD(806, 260) = ( 806 x 260 ) / 8060

= 806 / 260

= 806

Step2:

LCM(26, 138) = 1794

GCD(26, 138) = ( 26 x 138 ) / 1794

= 26 / 138

= 26

Step3:

LCM(2, 477) = 954

GCD(2, 477) = ( 2 x 477 ) / 954

= 2 / 477

= 2

So, Greatest Common Divisor of 806, 260, 138, 477 is 1
