Given numbers are 135, 621, 820, 865

The list of prime factors of all numbers are

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 865 are 5 x 173

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

Given numbers are 135, 621, 820, 865

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

Apply this formula for all numbers.

Step1:

LCM(135, 621) = 3105

GCD(135, 621) = ( 135 x 621 ) / 3105

= 135 / 621

= 135

Step2:

LCM(27, 820) = 22140

GCD(27, 820) = ( 27 x 820 ) / 22140

= 27 / 820

= 27

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 135, 621, 820, 865 is 1
