Given numbers are 221, 620, 768, 965

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

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

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 965 are 5 x 193

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

Given numbers are 221, 620, 768, 965

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

Apply this formula for all numbers.

Step1:

LCM(221, 620) = 137020

GCD(221, 620) = ( 221 x 620 ) / 137020

= 221 / 620

= 221

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 221, 620, 768, 965 is 1
