Given numbers are 620, 205, 663, 265

The list of prime factors of all numbers are

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

Prime factors of 205 are 5 x 41

Prime factors of 663 are 3 x 13 x 17

Prime factors of 265 are 5 x 53

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

Given numbers are 620, 205, 663, 265

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

Apply this formula for all numbers.

Step1:

LCM(620, 205) = 25420

GCD(620, 205) = ( 620 x 205 ) / 25420

= 620 / 205

= 620

Step2:

LCM(5, 663) = 3315

GCD(5, 663) = ( 5 x 663 ) / 3315

= 5 / 663

= 5

Step3:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

So, Greatest Common Divisor of 620, 205, 663, 265 is 1
