Given numbers are 220, 940, 305, 128

The list of prime factors of all numbers are

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

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 305 are 5 x 61

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 220, 940, 305, 128

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

Apply this formula for all numbers.

Step1:

LCM(220, 940) = 10340

GCD(220, 940) = ( 220 x 940 ) / 10340

= 220 / 940

= 220

Step2:

LCM(20, 305) = 1220

GCD(20, 305) = ( 20 x 305 ) / 1220

= 20 / 305

= 20

Step3:

LCM(5, 128) = 640

GCD(5, 128) = ( 5 x 128 ) / 640

= 5 / 128

= 5

So, Greatest Common Divisor of 220, 940, 305, 128 is 1
