Given numbers are 665, 261, 890, 675

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 261 are 3 x 3 x 29

Prime factors of 890 are 2 x 5 x 89

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

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

Given numbers are 665, 261, 890, 675

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

Apply this formula for all numbers.

Step1:

LCM(665, 261) = 173565

GCD(665, 261) = ( 665 x 261 ) / 173565

= 665 / 261

= 665

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 675) = 675

GCD(1, 675) = ( 1 x 675 ) / 675

= 1 / 675

= 1

So, Greatest Common Divisor of 665, 261, 890, 675 is 1
