Given numbers are 182, 856, 961, 420

The list of prime factors of all numbers are

Prime factors of 182 are 2 x 7 x 13

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 961 are 31 x 31

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 182, 856, 961, 420

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

Apply this formula for all numbers.

Step1:

LCM(182, 856) = 77896

GCD(182, 856) = ( 182 x 856 ) / 77896

= 182 / 856

= 182

Step2:

LCM(2, 961) = 1922

GCD(2, 961) = ( 2 x 961 ) / 1922

= 2 / 961

= 2

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 182, 856, 961, 420 is 1
