Given numbers are 770, 666, 179, 189

The list of prime factors of all numbers are

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

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 179 are 179

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 770, 666, 179, 189

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

Apply this formula for all numbers.

Step1:

LCM(770, 666) = 256410

GCD(770, 666) = ( 770 x 666 ) / 256410

= 770 / 666

= 770

Step2:

LCM(2, 179) = 358

GCD(2, 179) = ( 2 x 179 ) / 358

= 2 / 179

= 2

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 770, 666, 179, 189 is 1
