Given numbers are 220, 431, 420, 677

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 431 are 431

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

Prime factors of 677 are 677

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

Given numbers are 220, 431, 420, 677

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

Apply this formula for all numbers.

Step1:

LCM(220, 431) = 94820

GCD(220, 431) = ( 220 x 431 ) / 94820

= 220 / 431

= 220

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 677) = 677

GCD(1, 677) = ( 1 x 677 ) / 677

= 1 / 677

= 1

So, Greatest Common Divisor of 220, 431, 420, 677 is 1
