Given numbers are 521, 660, 412, 478

The list of prime factors of all numbers are

Prime factors of 521 are 521

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

Prime factors of 412 are 2 x 2 x 103

Prime factors of 478 are 2 x 239

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

Given numbers are 521, 660, 412, 478

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

Apply this formula for all numbers.

Step1:

LCM(521, 660) = 343860

GCD(521, 660) = ( 521 x 660 ) / 343860

= 521 / 660

= 521

Step2:

LCM(1, 412) = 412

GCD(1, 412) = ( 1 x 412 ) / 412

= 1 / 412

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 521, 660, 412, 478 is 1
