Given numbers are 221, 554, 970, 312

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 554 are 2 x 277

Prime factors of 970 are 2 x 5 x 97

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, 554, 970, 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, 554) = 122434

GCD(221, 554) = ( 221 x 554 ) / 122434

= 221 / 554

= 221

Step2:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

Step3:

LCM(1, 312) = 312

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

= 1 / 312

= 1

So, Greatest Common Divisor of 221, 554, 970, 312 is 1
