Given numbers are 166, 415, 646, 513

The list of prime factors of all numbers are

Prime factors of 166 are 2 x 83

Prime factors of 415 are 5 x 83

Prime factors of 646 are 2 x 17 x 19

Prime factors of 513 are 3 x 3 x 3 x 19

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

Given numbers are 166, 415, 646, 513

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

Apply this formula for all numbers.

Step1:

LCM(166, 415) = 830

GCD(166, 415) = ( 166 x 415 ) / 830

= 166 / 415

= 166

Step2:

LCM(83, 646) = 53618

GCD(83, 646) = ( 83 x 646 ) / 53618

= 83 / 646

= 83

Step3:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 166, 415, 646, 513 is 1
