Given numbers are 445, 660, 567, 945

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 567 are 3 x 3 x 3 x 3 x 7

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

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

Given numbers are 445, 660, 567, 945

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

Apply this formula for all numbers.

Step1:

LCM(445, 660) = 58740

GCD(445, 660) = ( 445 x 660 ) / 58740

= 445 / 660

= 445

Step2:

LCM(5, 567) = 2835

GCD(5, 567) = ( 5 x 567 ) / 2835

= 5 / 567

= 5

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 445, 660, 567, 945 is 1
