Given numbers are 865, 290, 266, 980

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 290 are 2 x 5 x 29

Prime factors of 266 are 2 x 7 x 19

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 865, 290, 266, 980

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

Apply this formula for all numbers.

Step1:

LCM(865, 290) = 50170

GCD(865, 290) = ( 865 x 290 ) / 50170

= 865 / 290

= 865

Step2:

LCM(5, 266) = 1330

GCD(5, 266) = ( 5 x 266 ) / 1330

= 5 / 266

= 5

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 865, 290, 266, 980 is 1
