Given numbers are 876, 423, 213, 821

The list of prime factors of all numbers are

Prime factors of 876 are 2 x 2 x 3 x 73

Prime factors of 423 are 3 x 3 x 47

Prime factors of 213 are 3 x 71

Prime factors of 821 are 821

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

Given numbers are 876, 423, 213, 821

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

Apply this formula for all numbers.

Step1:

LCM(876, 423) = 123516

GCD(876, 423) = ( 876 x 423 ) / 123516

= 876 / 423

= 876

Step2:

LCM(3, 213) = 213

GCD(3, 213) = ( 3 x 213 ) / 213

= 3 / 213

= 3

Step3:

LCM(3, 821) = 2463

GCD(3, 821) = ( 3 x 821 ) / 2463

= 3 / 821

= 3

So, Greatest Common Divisor of 876, 423, 213, 821 is 1
