The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 455 are 5 x 7 x 13

Prime factors of 668 are 2 x 2 x 167

Prime factors of 934 are 2 x 467

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

Given numbers are 987, 455, 668, 934

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

Apply this formula for all numbers.

Step1:

LCM(987, 455) = 64155

GCD(987, 455) = ( 987 x 455 ) / 64155

= 987 / 455

= 987

Step2:

LCM(7, 668) = 4676

GCD(7, 668) = ( 7 x 668 ) / 4676

= 7 / 668

= 7

Step3:

LCM(1, 934) = 934

GCD(1, 934) = ( 1 x 934 ) / 934

= 1 / 934

= 1

So, Greatest Common Divisor of 987, 455, 668, 934 is 1
