Given numbers are 688, 720, 775, 207

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 775 are 5 x 5 x 31

Prime factors of 207 are 3 x 3 x 23

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

Given numbers are 688, 720, 775, 207

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

Apply this formula for all numbers.

Step1:

LCM(688, 720) = 30960

GCD(688, 720) = ( 688 x 720 ) / 30960

= 688 / 720

= 688

Step2:

LCM(16, 775) = 12400

GCD(16, 775) = ( 16 x 775 ) / 12400

= 16 / 775

= 16

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 688, 720, 775, 207 is 1
