Given numbers are 666, 390, 770, 965

The list of prime factors of all numbers are

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

Prime factors of 390 are 2 x 3 x 5 x 13

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

Prime factors of 965 are 5 x 193

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

Given numbers are 666, 390, 770, 965

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

Apply this formula for all numbers.

Step1:

LCM(666, 390) = 43290

GCD(666, 390) = ( 666 x 390 ) / 43290

= 666 / 390

= 666

Step2:

LCM(6, 770) = 2310

GCD(6, 770) = ( 6 x 770 ) / 2310

= 6 / 770

= 6

Step3:

LCM(2, 965) = 1930

GCD(2, 965) = ( 2 x 965 ) / 1930

= 2 / 965

= 2

So, Greatest Common Divisor of 666, 390, 770, 965 is 1
