Given numbers are 399, 308, 521, 540

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 521 are 521

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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

Given numbers are 399, 308, 521, 540

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

Apply this formula for all numbers.

Step1:

LCM(399, 308) = 17556

GCD(399, 308) = ( 399 x 308 ) / 17556

= 399 / 308

= 399

Step2:

LCM(7, 521) = 3647

GCD(7, 521) = ( 7 x 521 ) / 3647

= 7 / 521

= 7

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 399, 308, 521, 540 is 1
