Given numbers are 434, 609, 420, 451

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 609 are 3 x 7 x 29

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

Prime factors of 451 are 11 x 41

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

Given numbers are 434, 609, 420, 451

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

Apply this formula for all numbers.

Step1:

LCM(434, 609) = 37758

GCD(434, 609) = ( 434 x 609 ) / 37758

= 434 / 609

= 434

Step2:

LCM(7, 420) = 420

GCD(7, 420) = ( 7 x 420 ) / 420

= 7 / 420

= 7

Step3:

LCM(7, 451) = 3157

GCD(7, 451) = ( 7 x 451 ) / 3157

= 7 / 451

= 7

So, Greatest Common Divisor of 434, 609, 420, 451 is 1
