Given numbers are 420, 528, 819, 134

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 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 134 are 2 x 67

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

Given numbers are 420, 528, 819, 134

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

Apply this formula for all numbers.

Step1:

LCM(420, 528) = 18480

GCD(420, 528) = ( 420 x 528 ) / 18480

= 420 / 528

= 420

Step2:

LCM(12, 819) = 3276

GCD(12, 819) = ( 12 x 819 ) / 3276

= 12 / 819

= 12

Step3:

LCM(3, 134) = 402

GCD(3, 134) = ( 3 x 134 ) / 402

= 3 / 134

= 3

So, Greatest Common Divisor of 420, 528, 819, 134 is 1
