Given numbers are 620, 630, 205, 969

The list of prime factors of all numbers are

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

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 205 are 5 x 41

Prime factors of 969 are 3 x 17 x 19

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

Given numbers are 620, 630, 205, 969

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

Apply this formula for all numbers.

Step1:

LCM(620, 630) = 39060

GCD(620, 630) = ( 620 x 630 ) / 39060

= 620 / 630

= 620

Step2:

LCM(10, 205) = 410

GCD(10, 205) = ( 10 x 205 ) / 410

= 10 / 205

= 10

Step3:

LCM(5, 969) = 4845

GCD(5, 969) = ( 5 x 969 ) / 4845

= 5 / 969

= 5

So, Greatest Common Divisor of 620, 630, 205, 969 is 1
