Given numbers are 287, 186, 304, 220

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 186 are 2 x 3 x 31

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

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

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

Given numbers are 287, 186, 304, 220

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

Apply this formula for all numbers.

Step1:

LCM(287, 186) = 53382

GCD(287, 186) = ( 287 x 186 ) / 53382

= 287 / 186

= 287

Step2:

LCM(1, 304) = 304

GCD(1, 304) = ( 1 x 304 ) / 304

= 1 / 304

= 1

Step3:

LCM(1, 220) = 220

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

= 1 / 220

= 1

So, Greatest Common Divisor of 287, 186, 304, 220 is 1
