Given numbers are 645, 400, 682, 539

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 682 are 2 x 11 x 31

Prime factors of 539 are 7 x 7 x 11

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

Given numbers are 645, 400, 682, 539

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

Apply this formula for all numbers.

Step1:

LCM(645, 400) = 51600

GCD(645, 400) = ( 645 x 400 ) / 51600

= 645 / 400

= 645

Step2:

LCM(5, 682) = 3410

GCD(5, 682) = ( 5 x 682 ) / 3410

= 5 / 682

= 5

Step3:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

So, Greatest Common Divisor of 645, 400, 682, 539 is 1
