Given numbers are 261, 315, 861, 760

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 861 are 3 x 7 x 41

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

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

Given numbers are 261, 315, 861, 760

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

Apply this formula for all numbers.

Step1:

LCM(261, 315) = 9135

GCD(261, 315) = ( 261 x 315 ) / 9135

= 261 / 315

= 261

Step2:

LCM(9, 861) = 2583

GCD(9, 861) = ( 9 x 861 ) / 2583

= 9 / 861

= 9

Step3:

LCM(3, 760) = 2280

GCD(3, 760) = ( 3 x 760 ) / 2280

= 3 / 760

= 3

So, Greatest Common Divisor of 261, 315, 861, 760 is 1
