Given numbers are 987, 213, 884, 121

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 213 are 3 x 71

Prime factors of 884 are 2 x 2 x 13 x 17

Prime factors of 121 are 11 x 11

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

Given numbers are 987, 213, 884, 121

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

Apply this formula for all numbers.

Step1:

LCM(987, 213) = 70077

GCD(987, 213) = ( 987 x 213 ) / 70077

= 987 / 213

= 987

Step2:

LCM(3, 884) = 2652

GCD(3, 884) = ( 3 x 884 ) / 2652

= 3 / 884

= 3

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 987, 213, 884, 121 is 1
