Given numbers are 945, 880, 420, 831

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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

Prime factors of 831 are 3 x 277

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

Given numbers are 945, 880, 420, 831

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

Apply this formula for all numbers.

Step1:

LCM(945, 880) = 166320

GCD(945, 880) = ( 945 x 880 ) / 166320

= 945 / 880

= 945

Step2:

LCM(5, 420) = 420

GCD(5, 420) = ( 5 x 420 ) / 420

= 5 / 420

= 5

Step3:

LCM(5, 831) = 4155

GCD(5, 831) = ( 5 x 831 ) / 4155

= 5 / 831

= 5

So, Greatest Common Divisor of 945, 880, 420, 831 is 1
