Given numbers are 655, 623, 630, 254

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 623 are 7 x 89

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 254 are 2 x 127

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

Given numbers are 655, 623, 630, 254

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

Apply this formula for all numbers.

Step1:

LCM(655, 623) = 408065

GCD(655, 623) = ( 655 x 623 ) / 408065

= 655 / 623

= 655

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 655, 623, 630, 254 is 1
