Given numbers are 690, 845, 446, 669

The list of prime factors of all numbers are

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

Prime factors of 845 are 5 x 13 x 13

Prime factors of 446 are 2 x 223

Prime factors of 669 are 3 x 223

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

Given numbers are 690, 845, 446, 669

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

Apply this formula for all numbers.

Step1:

LCM(690, 845) = 116610

GCD(690, 845) = ( 690 x 845 ) / 116610

= 690 / 845

= 690

Step2:

LCM(5, 446) = 2230

GCD(5, 446) = ( 5 x 446 ) / 2230

= 5 / 446

= 5

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 690, 845, 446, 669 is 1
