Given numbers are 671, 109, 477, 420

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 109 are 109

Prime factors of 477 are 3 x 3 x 53

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

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

Given numbers are 671, 109, 477, 420

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

Apply this formula for all numbers.

Step1:

LCM(671, 109) = 73139

GCD(671, 109) = ( 671 x 109 ) / 73139

= 671 / 109

= 671

Step2:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 671, 109, 477, 420 is 1
