Given numbers are 945, 452, 669, 121

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 452 are 2 x 2 x 113

Prime factors of 669 are 3 x 223

Prime factors of 121 are 11 x 11

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

Given numbers are 945, 452, 669, 121

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

Apply this formula for all numbers.

Step1:

LCM(945, 452) = 427140

GCD(945, 452) = ( 945 x 452 ) / 427140

= 945 / 452

= 945

Step2:

LCM(1, 669) = 669

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

= 1 / 669

= 1

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 945, 452, 669, 121 is 1
