Given numbers are 430, 407, 840, 434

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 407 are 11 x 37

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 430, 407, 840, 434

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

Apply this formula for all numbers.

Step1:

LCM(430, 407) = 175010

GCD(430, 407) = ( 430 x 407 ) / 175010

= 430 / 407

= 430

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 430, 407, 840, 434 is 1
