Given numbers are 420, 348, 660, 854

The list of prime factors of all numbers are

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

Prime factors of 348 are 2 x 2 x 3 x 29

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 854 are 2 x 7 x 61

The highest common occurrence is 2¹

Therefore, GCD of 420, 348, 660, 854 is 2.

Given numbers are 420, 348, 660, 854

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

Apply this formula for all numbers.

Step1:

LCM(420, 348) = 12180

GCD(420, 348) = ( 420 x 348 ) / 12180

= 420 / 348

= 420

Step2:

LCM(12, 660) = 660

GCD(12, 660) = ( 12 x 660 ) / 660

= 12 / 660

= 12

Step3:

LCM(12, 854) = 5124

GCD(12, 854) = ( 12 x 854 ) / 5124

= 12 / 854

= 12

So, Greatest Common Divisor of 420, 348, 660, 854 is 2
