Given numbers are 971, 520, 666, 305

The list of prime factors of all numbers are

Prime factors of 971 are 971

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

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 971, 520, 666, 305

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

Apply this formula for all numbers.

Step1:

LCM(971, 520) = 504920

GCD(971, 520) = ( 971 x 520 ) / 504920

= 971 / 520

= 971

Step2:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

Step3:

LCM(1, 305) = 305

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

= 1 / 305

= 1

So, Greatest Common Divisor of 971, 520, 666, 305 is 1
