Given numbers are 788, 561, 507, 770

The list of prime factors of all numbers are

Prime factors of 788 are 2 x 2 x 197

Prime factors of 561 are 3 x 11 x 17

Prime factors of 507 are 3 x 13 x 13

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

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

Given numbers are 788, 561, 507, 770

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

Apply this formula for all numbers.

Step1:

LCM(788, 561) = 442068

GCD(788, 561) = ( 788 x 561 ) / 442068

= 788 / 561

= 788

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 788, 561, 507, 770 is 1
