Given numbers are 220, 198, 756, 775

The list of prime factors of all numbers are

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

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 775 are 5 x 5 x 31

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

Given numbers are 220, 198, 756, 775

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

Apply this formula for all numbers.

Step1:

LCM(220, 198) = 1980

GCD(220, 198) = ( 220 x 198 ) / 1980

= 220 / 198

= 220

Step2:

LCM(22, 756) = 8316

GCD(22, 756) = ( 22 x 756 ) / 8316

= 22 / 756

= 22

Step3:

LCM(2, 775) = 1550

GCD(2, 775) = ( 2 x 775 ) / 1550

= 2 / 775

= 2

So, Greatest Common Divisor of 220, 198, 756, 775 is 1
