The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 121 are 11 x 11

Prime factors of 913 are 11 x 83

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

Given numbers are 987, 340, 121, 913

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

Apply this formula for all numbers.

Step1:

LCM(987, 340) = 335580

GCD(987, 340) = ( 987 x 340 ) / 335580

= 987 / 340

= 987

Step2:

LCM(1, 121) = 121

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

= 1 / 121

= 1

Step3:

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

= 1 / 913

= 1

So, Greatest Common Divisor of 987, 340, 121, 913 is 1
