Given numbers are 430, 438, 129, 148

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 438 are 2 x 3 x 73

Prime factors of 129 are 3 x 43

Prime factors of 148 are 2 x 2 x 37

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

Given numbers are 430, 438, 129, 148

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

Apply this formula for all numbers.

Step1:

LCM(430, 438) = 94170

GCD(430, 438) = ( 430 x 438 ) / 94170

= 430 / 438

= 430

Step2:

LCM(2, 129) = 258

GCD(2, 129) = ( 2 x 129 ) / 258

= 2 / 129

= 2

Step3:

LCM(1, 148) = 148

GCD(1, 148) = ( 1 x 148 ) / 148

= 1 / 148

= 1

So, Greatest Common Divisor of 430, 438, 129, 148 is 1
