Given numbers are 821, 836, 889, 456

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 889 are 7 x 127

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 821, 836, 889, 456

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

Apply this formula for all numbers.

Step1:

LCM(821, 836) = 686356

GCD(821, 836) = ( 821 x 836 ) / 686356

= 821 / 836

= 821

Step2:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 821, 836, 889, 456 is 1
