Given numbers are 990, 755, 685, 669

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 755 are 5 x 151

Prime factors of 685 are 5 x 137

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 990, 755, 685, 669

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

Apply this formula for all numbers.

Step1:

LCM(990, 755) = 149490

GCD(990, 755) = ( 990 x 755 ) / 149490

= 990 / 755

= 990

Step2:

LCM(5, 685) = 685

GCD(5, 685) = ( 5 x 685 ) / 685

= 5 / 685

= 5

Step3:

LCM(5, 669) = 3345

GCD(5, 669) = ( 5 x 669 ) / 3345

= 5 / 669

= 5

So, Greatest Common Divisor of 990, 755, 685, 669 is 1
