Given numbers are 261, 103, 690, 506

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 103 are 103

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 261, 103, 690, 506

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

Apply this formula for all numbers.

Step1:

LCM(261, 103) = 26883

GCD(261, 103) = ( 261 x 103 ) / 26883

= 261 / 103

= 261

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 506) = 506

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

= 1 / 506

= 1

So, Greatest Common Divisor of 261, 103, 690, 506 is 1
