Given numbers are 287, 679, 440, 920

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 679 are 7 x 97

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

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 287, 679, 440, 920

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

Apply this formula for all numbers.

Step1:

LCM(287, 679) = 27839

GCD(287, 679) = ( 287 x 679 ) / 27839

= 287 / 679

= 287

Step2:

LCM(7, 440) = 3080

GCD(7, 440) = ( 7 x 440 ) / 3080

= 7 / 440

= 7

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 287, 679, 440, 920 is 1
