Given numbers are 945, 325, 411, 561

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 325 are 5 x 5 x 13

Prime factors of 411 are 3 x 137

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 945, 325, 411, 561

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

Apply this formula for all numbers.

Step1:

LCM(945, 325) = 61425

GCD(945, 325) = ( 945 x 325 ) / 61425

= 945 / 325

= 945

Step2:

LCM(5, 411) = 2055

GCD(5, 411) = ( 5 x 411 ) / 2055

= 5 / 411

= 5

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 945, 325, 411, 561 is 1
