Given numbers are 663, 531, 655, 574

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 531 are 3 x 3 x 59

Prime factors of 655 are 5 x 131

Prime factors of 574 are 2 x 7 x 41

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

Given numbers are 663, 531, 655, 574

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

Apply this formula for all numbers.

Step1:

LCM(663, 531) = 117351

GCD(663, 531) = ( 663 x 531 ) / 117351

= 663 / 531

= 663

Step2:

LCM(3, 655) = 1965

GCD(3, 655) = ( 3 x 655 ) / 1965

= 3 / 655

= 3

Step3:

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

= 1 / 574

= 1

So, Greatest Common Divisor of 663, 531, 655, 574 is 1
