Given numbers are 987, 324, 813, 550

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 813 are 3 x 271

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 987, 324, 813, 550

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

Apply this formula for all numbers.

Step1:

LCM(987, 324) = 106596

GCD(987, 324) = ( 987 x 324 ) / 106596

= 987 / 324

= 987

Step2:

LCM(3, 813) = 813

GCD(3, 813) = ( 3 x 813 ) / 813

= 3 / 813

= 3

Step3:

LCM(3, 550) = 1650

GCD(3, 550) = ( 3 x 550 ) / 1650

= 3 / 550

= 3

So, Greatest Common Divisor of 987, 324, 813, 550 is 1
