Given numbers are 987, 432, 223, 631

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 223 are 223

Prime factors of 631 are 631

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

Given numbers are 987, 432, 223, 631

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

Apply this formula for all numbers.

Step1:

LCM(987, 432) = 142128

GCD(987, 432) = ( 987 x 432 ) / 142128

= 987 / 432

= 987

Step2:

LCM(3, 223) = 669

GCD(3, 223) = ( 3 x 223 ) / 669

= 3 / 223

= 3

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 987, 432, 223, 631 is 1
