Given numbers are 620, 805, 836, 805

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 805 are 5 x 7 x 23

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 620, 805, 836, 805

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

Apply this formula for all numbers.

Step1:

LCM(620, 805) = 99820

GCD(620, 805) = ( 620 x 805 ) / 99820

= 620 / 805

= 620

Step2:

LCM(5, 836) = 4180

GCD(5, 836) = ( 5 x 836 ) / 4180

= 5 / 836

= 5

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 620, 805, 836, 805 is 1
