Given numbers are 261, 868, 372, 380

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 380 are 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, 868, 372, 380

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

Apply this formula for all numbers.

Step1:

LCM(261, 868) = 226548

GCD(261, 868) = ( 261 x 868 ) / 226548

= 261 / 868

= 261

Step2:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 261, 868, 372, 380 is 1
