Given numbers are 130, 645, 517, 217

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 517 are 11 x 47

Prime factors of 217 are 7 x 31

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

Given numbers are 130, 645, 517, 217

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

Apply this formula for all numbers.

Step1:

LCM(130, 645) = 16770

GCD(130, 645) = ( 130 x 645 ) / 16770

= 130 / 645

= 130

Step2:

LCM(5, 517) = 2585

GCD(5, 517) = ( 5 x 517 ) / 2585

= 5 / 517

= 5

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 130, 645, 517, 217 is 1
