Given numbers are 987, 988, 144, 228

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 228 are 2 x 2 x 3 x 19

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

Given numbers are 987, 988, 144, 228

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

Apply this formula for all numbers.

Step1:

LCM(987, 988) = 975156

GCD(987, 988) = ( 987 x 988 ) / 975156

= 987 / 988

= 987

Step2:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 987, 988, 144, 228 is 1
