Given numbers are 122, 775, 220, 320

The list of prime factors of all numbers are

Prime factors of 122 are 2 x 61

Prime factors of 775 are 5 x 5 x 31

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

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 122, 775, 220, 320

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

Apply this formula for all numbers.

Step1:

LCM(122, 775) = 94550

GCD(122, 775) = ( 122 x 775 ) / 94550

= 122 / 775

= 122

Step2:

LCM(1, 220) = 220

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

= 1 / 220

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 122, 775, 220, 320 is 1
