Given numbers are 987, 424, 679, 440

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 679 are 7 x 97

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 987, 424, 679, 440

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

Apply this formula for all numbers.

Step1:

LCM(987, 424) = 418488

GCD(987, 424) = ( 987 x 424 ) / 418488

= 987 / 424

= 987

Step2:

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

= 1 / 679

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 987, 424, 679, 440 is 1
