Given numbers are 220, 985, 397, 428

The list of prime factors of all numbers are

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

Prime factors of 985 are 5 x 197

Prime factors of 397 are 397

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 220, 985, 397, 428

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

Apply this formula for all numbers.

Step1:

LCM(220, 985) = 43340

GCD(220, 985) = ( 220 x 985 ) / 43340

= 220 / 985

= 220

Step2:

LCM(5, 397) = 1985

GCD(5, 397) = ( 5 x 397 ) / 1985

= 5 / 397

= 5

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 220, 985, 397, 428 is 1
