Given numbers are 685, 656, 201, 807

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 201 are 3 x 67

Prime factors of 807 are 3 x 269

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

Given numbers are 685, 656, 201, 807

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

Apply this formula for all numbers.

Step1:

LCM(685, 656) = 449360

GCD(685, 656) = ( 685 x 656 ) / 449360

= 685 / 656

= 685

Step2:

LCM(1, 201) = 201

GCD(1, 201) = ( 1 x 201 ) / 201

= 1 / 201

= 1

Step3:

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

= 1 / 807

= 1

So, Greatest Common Divisor of 685, 656, 201, 807 is 1
