Given numbers are 521, 665, 224, 168

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 665 are 5 x 7 x 19

Prime factors of 224 are 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 168 are 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 521, 665, 224, 168

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

Apply this formula for all numbers.

Step1:

LCM(521, 665) = 346465

GCD(521, 665) = ( 521 x 665 ) / 346465

= 521 / 665

= 521

Step2:

LCM(1, 224) = 224

GCD(1, 224) = ( 1 x 224 ) / 224

= 1 / 224

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 521, 665, 224, 168 is 1
