Given numbers are 221, 867, 370, 312

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 867 are 3 x 17 x 17

Prime factors of 370 are 2 x 5 x 37

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 221, 867, 370, 312

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

Apply this formula for all numbers.

Step1:

LCM(221, 867) = 11271

GCD(221, 867) = ( 221 x 867 ) / 11271

= 221 / 867

= 221

Step2:

LCM(17, 370) = 6290

GCD(17, 370) = ( 17 x 370 ) / 6290

= 17 / 370

= 17

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 221, 867, 370, 312 is 1
