Given numbers are 987, 126, 284, 558

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 284 are 2 x 2 x 71

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 987, 126, 284, 558

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

Apply this formula for all numbers.

Step1:

LCM(987, 126) = 5922

GCD(987, 126) = ( 987 x 126 ) / 5922

= 987 / 126

= 987

Step2:

LCM(21, 284) = 5964

GCD(21, 284) = ( 21 x 284 ) / 5964

= 21 / 284

= 21

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 987, 126, 284, 558 is 1
