Given numbers are 261, 857, 504, 813

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 857 are 857

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 813 are 3 x 271

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

Given numbers are 261, 857, 504, 813

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

Apply this formula for all numbers.

Step1:

LCM(261, 857) = 223677

GCD(261, 857) = ( 261 x 857 ) / 223677

= 261 / 857

= 261

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 261, 857, 504, 813 is 1
