Given numbers are 660, 665, 788, 305

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 665 are 5 x 7 x 19

Prime factors of 788 are 2 x 2 x 197

Prime factors of 305 are 5 x 61

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

Given numbers are 660, 665, 788, 305

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

Apply this formula for all numbers.

Step1:

LCM(660, 665) = 87780

GCD(660, 665) = ( 660 x 665 ) / 87780

= 660 / 665

= 660

Step2:

LCM(5, 788) = 3940

GCD(5, 788) = ( 5 x 788 ) / 3940

= 5 / 788

= 5

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 660, 665, 788, 305 is 1
