Given numbers are 213, 469, 820, 378

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

Prime factors of 469 are 7 x 67

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 213, 469, 820, 378

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

Apply this formula for all numbers.

Step1:

LCM(213, 469) = 99897

GCD(213, 469) = ( 213 x 469 ) / 99897

= 213 / 469

= 213

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 213, 469, 820, 378 is 1
