Given numbers are 516, 406, 640, 885

The list of prime factors of all numbers are

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

Prime factors of 406 are 2 x 7 x 29

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 885 are 3 x 5 x 59

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

Given numbers are 516, 406, 640, 885

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

Apply this formula for all numbers.

Step1:

LCM(516, 406) = 104748

GCD(516, 406) = ( 516 x 406 ) / 104748

= 516 / 406

= 516

Step2:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

Step3:

LCM(2, 885) = 1770

GCD(2, 885) = ( 2 x 885 ) / 1770

= 2 / 885

= 2

So, Greatest Common Divisor of 516, 406, 640, 885 is 1
