Given numbers are 668, 704, 636, 561

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

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

Prime factors of 636 are 2 x 2 x 3 x 53

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 668, 704, 636, 561

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

Apply this formula for all numbers.

Step1:

LCM(668, 704) = 117568

GCD(668, 704) = ( 668 x 704 ) / 117568

= 668 / 704

= 668

Step2:

LCM(4, 636) = 636

GCD(4, 636) = ( 4 x 636 ) / 636

= 4 / 636

= 4

Step3:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

So, Greatest Common Divisor of 668, 704, 636, 561 is 1
