Given numbers are 561, 664, 513, 954

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 954 are 2 x 3 x 3 x 53

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

Given numbers are 561, 664, 513, 954

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

Apply this formula for all numbers.

Step1:

LCM(561, 664) = 372504

GCD(561, 664) = ( 561 x 664 ) / 372504

= 561 / 664

= 561

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

Step3:

LCM(1, 954) = 954

GCD(1, 954) = ( 1 x 954 ) / 954

= 1 / 954

= 1

So, Greatest Common Divisor of 561, 664, 513, 954 is 1
