Given numbers are 820, 403, 554, 772

The list of prime factors of all numbers are

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

Prime factors of 403 are 13 x 31

Prime factors of 554 are 2 x 277

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 820, 403, 554, 772

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

Apply this formula for all numbers.

Step1:

LCM(820, 403) = 330460

GCD(820, 403) = ( 820 x 403 ) / 330460

= 820 / 403

= 820

Step2:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 820, 403, 554, 772 is 1
