Given numbers are 140, 966, 855, 961

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 961 are 31 x 31

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

Given numbers are 140, 966, 855, 961

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

Apply this formula for all numbers.

Step1:

LCM(140, 966) = 9660

GCD(140, 966) = ( 140 x 966 ) / 9660

= 140 / 966

= 140

Step2:

LCM(14, 855) = 11970

GCD(14, 855) = ( 14 x 855 ) / 11970

= 14 / 855

= 14

Step3:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

So, Greatest Common Divisor of 140, 966, 855, 961 is 1
