Given numbers are 253, 215, 506, 561

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 215 are 5 x 43

Prime factors of 506 are 2 x 11 x 23

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 253, 215, 506, 561

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

Apply this formula for all numbers.

Step1:

LCM(253, 215) = 54395

GCD(253, 215) = ( 253 x 215 ) / 54395

= 253 / 215

= 253

Step2:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 253, 215, 506, 561 is 1
