The list of prime factors of all numbers are

Prime factors of 772 are 2 x 2 x 193

Prime factors of 848 are 2 x 2 x 2 x 2 x 53

Prime factors of 820 are 2 x 2 x 5 x 41

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

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

Given numbers are 772, 848, 820, 945

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

Apply this formula for all numbers.

Step1:

LCM(772, 848) = 163664

GCD(772, 848) = ( 772 x 848 ) / 163664

= 772 / 848

= 772

Step2:

LCM(4, 820) = 820

GCD(4, 820) = ( 4 x 820 ) / 820

= 4 / 820

= 4

Step3:

LCM(4, 945) = 3780

GCD(4, 945) = ( 4 x 945 ) / 3780

= 4 / 945

= 4

So, Greatest Common Divisor of 772, 848, 820, 945 is 1
