Given numbers are 421, 280, 628, 726

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 628 are 2 x 2 x 157

Prime factors of 726 are 2 x 3 x 11 x 11

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

Given numbers are 421, 280, 628, 726

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

Apply this formula for all numbers.

Step1:

LCM(421, 280) = 117880

GCD(421, 280) = ( 421 x 280 ) / 117880

= 421 / 280

= 421

Step2:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

Step3:

LCM(1, 726) = 726

GCD(1, 726) = ( 1 x 726 ) / 726

= 1 / 726

= 1

So, Greatest Common Divisor of 421, 280, 628, 726 is 1
