Given numbers are 645, 245, 534, 694

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 245 are 5 x 7 x 7

Prime factors of 534 are 2 x 3 x 89

Prime factors of 694 are 2 x 347

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

Given numbers are 645, 245, 534, 694

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

Apply this formula for all numbers.

Step1:

LCM(645, 245) = 31605

GCD(645, 245) = ( 645 x 245 ) / 31605

= 645 / 245

= 645

Step2:

LCM(5, 534) = 2670

GCD(5, 534) = ( 5 x 534 ) / 2670

= 5 / 534

= 5

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 645, 245, 534, 694 is 1
