Given numbers are 685, 561, 864, 932

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 561 are 3 x 11 x 17

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 932 are 2 x 2 x 233

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

Given numbers are 685, 561, 864, 932

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

Apply this formula for all numbers.

Step1:

LCM(685, 561) = 384285

GCD(685, 561) = ( 685 x 561 ) / 384285

= 685 / 561

= 685

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 932) = 932

GCD(1, 932) = ( 1 x 932 ) / 932

= 1 / 932

= 1

So, Greatest Common Divisor of 685, 561, 864, 932 is 1
