Given numbers are 261, 550, 513, 678

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 678 are 2 x 3 x 113

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

Given numbers are 261, 550, 513, 678

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

Apply this formula for all numbers.

Step1:

LCM(261, 550) = 143550

GCD(261, 550) = ( 261 x 550 ) / 143550

= 261 / 550

= 261

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 261, 550, 513, 678 is 1
