Given numbers are 521, 552, 643, 747

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

Prime factors of 643 are 643

Prime factors of 747 are 3 x 3 x 83

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

Given numbers are 521, 552, 643, 747

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

Apply this formula for all numbers.

Step1:

LCM(521, 552) = 287592

GCD(521, 552) = ( 521 x 552 ) / 287592

= 521 / 552

= 521

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 521, 552, 643, 747 is 1
