Given numbers are 287, 123, 140

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 123 are 3 x 41

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 287, 123, 140

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

Apply this formula for all numbers.

Step1:

LCM(287, 123) = 861

GCD(287, 123) = ( 287 x 123 ) / 861

= 287 / 123

= 287

Step2:

LCM(41, 140) = 5740

GCD(41, 140) = ( 41 x 140 ) / 5740

= 41 / 140

= 41

So, Greatest Common Divisor of 287, 123, 140 is 1
