Given numbers are 214, 640, 940, 823

The list of prime factors of all numbers are

Prime factors of 214 are 2 x 107

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

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 823 are 823

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

Given numbers are 214, 640, 940, 823

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

Apply this formula for all numbers.

Step1:

LCM(214, 640) = 68480

GCD(214, 640) = ( 214 x 640 ) / 68480

= 214 / 640

= 214

Step2:

LCM(2, 940) = 940

GCD(2, 940) = ( 2 x 940 ) / 940

= 2 / 940

= 2

Step3:

LCM(2, 823) = 1646

GCD(2, 823) = ( 2 x 823 ) / 1646

= 2 / 823

= 2

So, Greatest Common Divisor of 214, 640, 940, 823 is 1
