Given numbers are 835, 547, 216, 420

The list of prime factors of all numbers are

Prime factors of 835 are 5 x 167

Prime factors of 547 are 547

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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 835, 547, 216, 420

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

Apply this formula for all numbers.

Step1:

LCM(835, 547) = 456745

GCD(835, 547) = ( 835 x 547 ) / 456745

= 835 / 547

= 835

Step2:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 835, 547, 216, 420 is 1
