Given numbers are 565, 860, 258, 646

The list of prime factors of all numbers are

Prime factors of 565 are 5 x 113

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 258 are 2 x 3 x 43

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 565, 860, 258, 646

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

Apply this formula for all numbers.

Step1:

LCM(565, 860) = 97180

GCD(565, 860) = ( 565 x 860 ) / 97180

= 565 / 860

= 565

Step2:

LCM(5, 258) = 1290

GCD(5, 258) = ( 5 x 258 ) / 1290

= 5 / 258

= 5

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 565, 860, 258, 646 is 1
