Given numbers are 665, 411, 568, 771

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 411 are 3 x 137

Prime factors of 568 are 2 x 2 x 2 x 71

Prime factors of 771 are 3 x 257

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

Given numbers are 665, 411, 568, 771

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

Apply this formula for all numbers.

Step1:

LCM(665, 411) = 273315

GCD(665, 411) = ( 665 x 411 ) / 273315

= 665 / 411

= 665

Step2:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 665, 411, 568, 771 is 1
