Given numbers are 885, 516, 485, 420

The list of prime factors of all numbers are

Prime factors of 885 are 3 x 5 x 59

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

Prime factors of 485 are 5 x 97

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 885, 516, 485, 420

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

Apply this formula for all numbers.

Step1:

LCM(885, 516) = 152220

GCD(885, 516) = ( 885 x 516 ) / 152220

= 885 / 516

= 885

Step2:

LCM(3, 485) = 1455

GCD(3, 485) = ( 3 x 485 ) / 1455

= 3 / 485

= 3

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 885, 516, 485, 420 is 1
