Given numbers are 987, 966, 115, 136

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 115 are 5 x 23

Prime factors of 136 are 2 x 2 x 2 x 17

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

Given numbers are 987, 966, 115, 136

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

Apply this formula for all numbers.

Step1:

LCM(987, 966) = 45402

GCD(987, 966) = ( 987 x 966 ) / 45402

= 987 / 966

= 987

Step2:

LCM(21, 115) = 2415

GCD(21, 115) = ( 21 x 115 ) / 2415

= 21 / 115

= 21

Step3:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

So, Greatest Common Divisor of 987, 966, 115, 136 is 1
