Given numbers are 246, 561, 640, 687

The list of prime factors of all numbers are

Prime factors of 246 are 2 x 3 x 41

Prime factors of 561 are 3 x 11 x 17

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 687 are 3 x 229

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

Given numbers are 246, 561, 640, 687

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

Apply this formula for all numbers.

Step1:

LCM(246, 561) = 46002

GCD(246, 561) = ( 246 x 561 ) / 46002

= 246 / 561

= 246

Step2:

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

= 3 / 640

= 3

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 246, 561, 640, 687 is 1
