Given numbers are 780, 183, 263, 561

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 183 are 3 x 61

Prime factors of 263 are 263

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 780, 183, 263, 561

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

Apply this formula for all numbers.

Step1:

LCM(780, 183) = 47580

GCD(780, 183) = ( 780 x 183 ) / 47580

= 780 / 183

= 780

Step2:

LCM(3, 263) = 789

GCD(3, 263) = ( 3 x 263 ) / 789

= 3 / 263

= 3

Step3:

LCM(1, 561) = 561

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

= 1 / 561

= 1

So, Greatest Common Divisor of 780, 183, 263, 561 is 1
