Given numbers are 130, 221, 687, 462

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 221 are 13 x 17

Prime factors of 687 are 3 x 229

Prime factors of 462 are 2 x 3 x 7 x 11

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

Given numbers are 130, 221, 687, 462

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

Apply this formula for all numbers.

Step1:

LCM(130, 221) = 2210

GCD(130, 221) = ( 130 x 221 ) / 2210

= 130 / 221

= 130

Step2:

LCM(13, 687) = 8931

GCD(13, 687) = ( 13 x 687 ) / 8931

= 13 / 687

= 13

Step3:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

So, Greatest Common Divisor of 130, 221, 687, 462 is 1
