Given numbers are 430, 706, 420, 655

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 706 are 2 x 353

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

Prime factors of 655 are 5 x 131

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

Given numbers are 430, 706, 420, 655

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

Apply this formula for all numbers.

Step1:

LCM(430, 706) = 151790

GCD(430, 706) = ( 430 x 706 ) / 151790

= 430 / 706

= 430

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 655) = 1310

GCD(2, 655) = ( 2 x 655 ) / 1310

= 2 / 655

= 2

So, Greatest Common Divisor of 430, 706, 420, 655 is 1
