Given numbers are 695, 240, 645, 281

The list of prime factors of all numbers are

Prime factors of 695 are 5 x 139

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 645 are 3 x 5 x 43

Prime factors of 281 are 281

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

Given numbers are 695, 240, 645, 281

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

Apply this formula for all numbers.

Step1:

LCM(695, 240) = 33360

GCD(695, 240) = ( 695 x 240 ) / 33360

= 695 / 240

= 695

Step2:

LCM(5, 645) = 645

GCD(5, 645) = ( 5 x 645 ) / 645

= 5 / 645

= 5

Step3:

LCM(5, 281) = 1405

GCD(5, 281) = ( 5 x 281 ) / 1405

= 5 / 281

= 5

So, Greatest Common Divisor of 695, 240, 645, 281 is 1
