Given numbers are 561, 252, 704, 672

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 561, 252, 704, 672

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

Apply this formula for all numbers.

Step1:

LCM(561, 252) = 47124

GCD(561, 252) = ( 561 x 252 ) / 47124

= 561 / 252

= 561

Step2:

LCM(3, 704) = 2112

GCD(3, 704) = ( 3 x 704 ) / 2112

= 3 / 704

= 3

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 561, 252, 704, 672 is 1
