Given numbers are 821, 200, 630, 427

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 427 are 7 x 61

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

Given numbers are 821, 200, 630, 427

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

Apply this formula for all numbers.

Step1:

LCM(821, 200) = 164200

GCD(821, 200) = ( 821 x 200 ) / 164200

= 821 / 200

= 821

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 821, 200, 630, 427 is 1
