Given numbers are 174, 490, 820, 261

The list of prime factors of all numbers are

Prime factors of 174 are 2 x 3 x 29

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 174, 490, 820, 261

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

Apply this formula for all numbers.

Step1:

LCM(174, 490) = 42630

GCD(174, 490) = ( 174 x 490 ) / 42630

= 174 / 490

= 174

Step2:

LCM(2, 820) = 820

GCD(2, 820) = ( 2 x 820 ) / 820

= 2 / 820

= 2

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 174, 490, 820, 261 is 1
