Given numbers are 690, 662, 640, 303

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 662 are 2 x 331

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

Prime factors of 303 are 3 x 101

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

Given numbers are 690, 662, 640, 303

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

Apply this formula for all numbers.

Step1:

LCM(690, 662) = 228390

GCD(690, 662) = ( 690 x 662 ) / 228390

= 690 / 662

= 690

Step2:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

Step3:

LCM(2, 303) = 606

GCD(2, 303) = ( 2 x 303 ) / 606

= 2 / 303

= 2

So, Greatest Common Divisor of 690, 662, 640, 303 is 1
