Given numbers are 987, 331, 240, 538

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 331 are 331

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 538 are 2 x 269

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

Given numbers are 987, 331, 240, 538

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

Apply this formula for all numbers.

Step1:

LCM(987, 331) = 326697

GCD(987, 331) = ( 987 x 331 ) / 326697

= 987 / 331

= 987

Step2:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 987, 331, 240, 538 is 1
