The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

Prime factors of 658 are 2 x 7 x 47

Prime factors of 842 are 2 x 421

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

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

Given numbers are 775, 658, 842, 720

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

Apply this formula for all numbers.

Step1:

LCM(775, 658) = 509950

GCD(775, 658) = ( 775 x 658 ) / 509950

= 775 / 658

= 775

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 775, 658, 842, 720 is 1
