Given numbers are 516, 861, 475, 408

The list of prime factors of all numbers are

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 861 are 3 x 7 x 41

Prime factors of 475 are 5 x 5 x 19

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 516, 861, 475, 408

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

Apply this formula for all numbers.

Step1:

LCM(516, 861) = 148092

GCD(516, 861) = ( 516 x 861 ) / 148092

= 516 / 861

= 516

Step2:

LCM(3, 475) = 1425

GCD(3, 475) = ( 3 x 475 ) / 1425

= 3 / 475

= 3

Step3:

LCM(1, 408) = 408

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

= 1 / 408

= 1

So, Greatest Common Divisor of 516, 861, 475, 408 is 1
