Given numbers are 821, 552, 400, 430

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 821, 552, 400, 430

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

Apply this formula for all numbers.

Step1:

LCM(821, 552) = 453192

GCD(821, 552) = ( 821 x 552 ) / 453192

= 821 / 552

= 821

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 821, 552, 400, 430 is 1
