Given numbers are 521, 380, 432, 649

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 649 are 11 x 59

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

Given numbers are 521, 380, 432, 649

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

Apply this formula for all numbers.

Step1:

LCM(521, 380) = 197980

GCD(521, 380) = ( 521 x 380 ) / 197980

= 521 / 380

= 521

Step2:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 521, 380, 432, 649 is 1
