Given numbers are 640, 237, 685, 818

The list of prime factors of all numbers are

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

Prime factors of 237 are 3 x 79

Prime factors of 685 are 5 x 137

Prime factors of 818 are 2 x 409

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

Given numbers are 640, 237, 685, 818

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

Apply this formula for all numbers.

Step1:

LCM(640, 237) = 151680

GCD(640, 237) = ( 640 x 237 ) / 151680

= 640 / 237

= 640

Step2:

LCM(1, 685) = 685

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

= 1 / 685

= 1

Step3:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 640, 237, 685, 818 is 1
