Given numbers are 938, 640, 275, 720

The list of prime factors of all numbers are

Prime factors of 938 are 2 x 7 x 67

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

Prime factors of 275 are 5 x 5 x 11

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

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

Given numbers are 938, 640, 275, 720

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

Apply this formula for all numbers.

Step1:

LCM(938, 640) = 300160

GCD(938, 640) = ( 938 x 640 ) / 300160

= 938 / 640

= 938

Step2:

LCM(2, 275) = 550

GCD(2, 275) = ( 2 x 275 ) / 550

= 2 / 275

= 2

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 938, 640, 275, 720 is 1
