Given numbers are 430, 687, 982, 138

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 687 are 3 x 229

Prime factors of 982 are 2 x 491

Prime factors of 138 are 2 x 3 x 23

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

Given numbers are 430, 687, 982, 138

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

Apply this formula for all numbers.

Step1:

LCM(430, 687) = 295410

GCD(430, 687) = ( 430 x 687 ) / 295410

= 430 / 687

= 430

Step2:

LCM(1, 982) = 982

GCD(1, 982) = ( 1 x 982 ) / 982

= 1 / 982

= 1

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 430, 687, 982, 138 is 1
