Given numbers are 765, 768, 772, 220

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

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 772 are 2 x 2 x 193

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 765, 768, 772, 220

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

Apply this formula for all numbers.

Step1:

LCM(765, 768) = 195840

GCD(765, 768) = ( 765 x 768 ) / 195840

= 765 / 768

= 765

Step2:

LCM(3, 772) = 2316

GCD(3, 772) = ( 3 x 772 ) / 2316

= 3 / 772

= 3

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 765, 768, 772, 220 is 1
