Given numbers are 254, 115, 565, 645

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 115 are 5 x 23

Prime factors of 565 are 5 x 113

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 254, 115, 565, 645

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

Apply this formula for all numbers.

Step1:

LCM(254, 115) = 29210

GCD(254, 115) = ( 254 x 115 ) / 29210

= 254 / 115

= 254

Step2:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 254, 115, 565, 645 is 1
