Given numbers are 645, 351, 253, 194

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 253 are 11 x 23

Prime factors of 194 are 2 x 97

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

Given numbers are 645, 351, 253, 194

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

Apply this formula for all numbers.

Step1:

LCM(645, 351) = 75465

GCD(645, 351) = ( 645 x 351 ) / 75465

= 645 / 351

= 645

Step2:

LCM(3, 253) = 759

GCD(3, 253) = ( 3 x 253 ) / 759

= 3 / 253

= 3

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 645, 351, 253, 194 is 1
