The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 938 are 2 x 7 x 67

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 987, 650, 938, 280

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

Apply this formula for all numbers.

Step1:

LCM(987, 650) = 641550

GCD(987, 650) = ( 987 x 650 ) / 641550

= 987 / 650

= 987

Step2:

LCM(1, 938) = 938

GCD(1, 938) = ( 1 x 938 ) / 938

= 1 / 938

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 987, 650, 938, 280 is 1
