Given numbers are 491, 393, 720, 772

The list of prime factors of all numbers are

Prime factors of 491 are 491

Prime factors of 393 are 3 x 131

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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 491, 393, 720, 772

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

Apply this formula for all numbers.

Step1:

LCM(491, 393) = 192963

GCD(491, 393) = ( 491 x 393 ) / 192963

= 491 / 393

= 491

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 772) = 772

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

= 1 / 772

= 1

So, Greatest Common Divisor of 491, 393, 720, 772 is 1
