Given numbers are 813, 540, 968, 408

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 968 are 2 x 2 x 2 x 11 x 11

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 813, 540, 968, 408

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

Apply this formula for all numbers.

Step1:

LCM(813, 540) = 146340

GCD(813, 540) = ( 813 x 540 ) / 146340

= 813 / 540

= 813

Step2:

LCM(3, 968) = 2904

GCD(3, 968) = ( 3 x 968 ) / 2904

= 3 / 968

= 3

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 813, 540, 968, 408 is 1
