Given numbers are 643, 390, 522, 532

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 532 are 2 x 2 x 7 x 19

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

Given numbers are 643, 390, 522, 532

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

Apply this formula for all numbers.

Step1:

LCM(643, 390) = 250770

GCD(643, 390) = ( 643 x 390 ) / 250770

= 643 / 390

= 643

Step2:

LCM(1, 522) = 522

GCD(1, 522) = ( 1 x 522 ) / 522

= 1 / 522

= 1

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 643, 390, 522, 532 is 1
