Given numbers are 612, 640, 43, 685

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 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 43 are 43

Prime factors of 685 are 5 x 137

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

Given numbers are 612, 640, 43, 685

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

Apply this formula for all numbers.

Step1:

LCM(612, 640) = 97920

GCD(612, 640) = ( 612 x 640 ) / 97920

= 612 / 640

= 612

Step2:

LCM(4, 43) = 172

GCD(4, 43) = ( 4 x 43 ) / 172

= 4 / 43

= 4

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 612, 640, 43, 685 is 1
