Given numbers are 681, 660, 326, 871

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 326 are 2 x 163

Prime factors of 871 are 13 x 67

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

Given numbers are 681, 660, 326, 871

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

Apply this formula for all numbers.

Step1:

LCM(681, 660) = 149820

GCD(681, 660) = ( 681 x 660 ) / 149820

= 681 / 660

= 681

Step2:

LCM(3, 326) = 978

GCD(3, 326) = ( 3 x 326 ) / 978

= 3 / 326

= 3

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 681, 660, 326, 871 is 1
