Given numbers are 645, 197, 514, 476

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 197 are 197

Prime factors of 514 are 2 x 257

Prime factors of 476 are 2 x 2 x 7 x 17

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

Given numbers are 645, 197, 514, 476

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

Apply this formula for all numbers.

Step1:

LCM(645, 197) = 127065

GCD(645, 197) = ( 645 x 197 ) / 127065

= 645 / 197

= 645

Step2:

LCM(1, 514) = 514

GCD(1, 514) = ( 1 x 514 ) / 514

= 1 / 514

= 1

Step3:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

So, Greatest Common Divisor of 645, 197, 514, 476 is 1
