Given numbers are 505, 231, 643, 536

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 231 are 3 x 7 x 11

Prime factors of 643 are 643

Prime factors of 536 are 2 x 2 x 2 x 67

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

Given numbers are 505, 231, 643, 536

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

Apply this formula for all numbers.

Step1:

LCM(505, 231) = 116655

GCD(505, 231) = ( 505 x 231 ) / 116655

= 505 / 231

= 505

Step2:

LCM(1, 643) = 643

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

= 1 / 643

= 1

Step3:

LCM(1, 536) = 536

GCD(1, 536) = ( 1 x 536 ) / 536

= 1 / 536

= 1

So, Greatest Common Divisor of 505, 231, 643, 536 is 1
