Given numbers are 685, 252, 931, 440

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 931 are 7 x 7 x 19

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 685, 252, 931, 440

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

Apply this formula for all numbers.

Step1:

LCM(685, 252) = 172620

GCD(685, 252) = ( 685 x 252 ) / 172620

= 685 / 252

= 685

Step2:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

Step3:

LCM(1, 440) = 440

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

= 1 / 440

= 1

So, Greatest Common Divisor of 685, 252, 931, 440 is 1
