Given numbers are 770, 507, 81, 775

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 507 are 3 x 13 x 13

Prime factors of 81 are 3 x 3 x 3 x 3

Prime factors of 775 are 5 x 5 x 31

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

Given numbers are 770, 507, 81, 775

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

Apply this formula for all numbers.

Step1:

LCM(770, 507) = 390390

GCD(770, 507) = ( 770 x 507 ) / 390390

= 770 / 507

= 770

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 770, 507, 81, 775 is 1
