Given numbers are 221, 525, 351, 988

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 525 are 3 x 5 x 5 x 7

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 988 are 2 x 2 x 13 x 19

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

Given numbers are 221, 525, 351, 988

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

Apply this formula for all numbers.

Step1:

LCM(221, 525) = 116025

GCD(221, 525) = ( 221 x 525 ) / 116025

= 221 / 525

= 221

Step2:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 221, 525, 351, 988 is 1
