Given numbers are 755, 810, 242, 646

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 242 are 2 x 11 x 11

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 755, 810, 242, 646

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

Apply this formula for all numbers.

Step1:

LCM(755, 810) = 122310

GCD(755, 810) = ( 755 x 810 ) / 122310

= 755 / 810

= 755

Step2:

LCM(5, 242) = 1210

GCD(5, 242) = ( 5 x 242 ) / 1210

= 5 / 242

= 5

Step3:

LCM(1, 646) = 646

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

= 1 / 646

= 1

So, Greatest Common Divisor of 755, 810, 242, 646 is 1
