Given numbers are 428, 220, 760, 239

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

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

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 239 are 239

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

Given numbers are 428, 220, 760, 239

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

Apply this formula for all numbers.

Step1:

LCM(428, 220) = 23540

GCD(428, 220) = ( 428 x 220 ) / 23540

= 428 / 220

= 428

Step2:

LCM(4, 760) = 760

GCD(4, 760) = ( 4 x 760 ) / 760

= 4 / 760

= 4

Step3:

LCM(4, 239) = 956

GCD(4, 239) = ( 4 x 239 ) / 956

= 4 / 239

= 4

So, Greatest Common Divisor of 428, 220, 760, 239 is 1
