Given numbers are 265, 561, 403, 426

The list of prime factors of all numbers are

Prime factors of 265 are 5 x 53

Prime factors of 561 are 3 x 11 x 17

Prime factors of 403 are 13 x 31

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 265, 561, 403, 426

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

Apply this formula for all numbers.

Step1:

LCM(265, 561) = 148665

GCD(265, 561) = ( 265 x 561 ) / 148665

= 265 / 561

= 265

Step2:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 265, 561, 403, 426 is 1
