Given numbers are 660, 561, 457, 590

The list of prime factors of all numbers are

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

Prime factors of 561 are 3 x 11 x 17

Prime factors of 457 are 457

Prime factors of 590 are 2 x 5 x 59

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

Given numbers are 660, 561, 457, 590

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

Apply this formula for all numbers.

Step1:

LCM(660, 561) = 11220

GCD(660, 561) = ( 660 x 561 ) / 11220

= 660 / 561

= 660

Step2:

LCM(33, 457) = 15081

GCD(33, 457) = ( 33 x 457 ) / 15081

= 33 / 457

= 33

Step3:

LCM(1, 590) = 590

GCD(1, 590) = ( 1 x 590 ) / 590

= 1 / 590

= 1

So, Greatest Common Divisor of 660, 561, 457, 590 is 1
