Given numbers are 881, 400, 420, 643

The list of prime factors of all numbers are

Prime factors of 881 are 881

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

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 643 are 643

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

Given numbers are 881, 400, 420, 643

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

Apply this formula for all numbers.

Step1:

LCM(881, 400) = 352400

GCD(881, 400) = ( 881 x 400 ) / 352400

= 881 / 400

= 881

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 881, 400, 420, 643 is 1
