Given numbers are 140, 484, 287, 865

The list of prime factors of all numbers are

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

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 287 are 7 x 41

Prime factors of 865 are 5 x 173

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

Given numbers are 140, 484, 287, 865

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

Apply this formula for all numbers.

Step1:

LCM(140, 484) = 16940

GCD(140, 484) = ( 140 x 484 ) / 16940

= 140 / 484

= 140

Step2:

LCM(4, 287) = 1148

GCD(4, 287) = ( 4 x 287 ) / 1148

= 4 / 287

= 4

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 140, 484, 287, 865 is 1
