Given numbers are 280, 470, 261, 578

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 470 are 2 x 5 x 47

Prime factors of 261 are 3 x 3 x 29

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 280, 470, 261, 578

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

Apply this formula for all numbers.

Step1:

LCM(280, 470) = 13160

GCD(280, 470) = ( 280 x 470 ) / 13160

= 280 / 470

= 280

Step2:

LCM(10, 261) = 2610

GCD(10, 261) = ( 10 x 261 ) / 2610

= 10 / 261

= 10

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 280, 470, 261, 578 is 1
