Given numbers are 354, 510, 166, 645

The list of prime factors of all numbers are

Prime factors of 354 are 2 x 3 x 59

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 166 are 2 x 83

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 354, 510, 166, 645

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

Apply this formula for all numbers.

Step1:

LCM(354, 510) = 30090

GCD(354, 510) = ( 354 x 510 ) / 30090

= 354 / 510

= 354

Step2:

LCM(6, 166) = 498

GCD(6, 166) = ( 6 x 166 ) / 498

= 6 / 166

= 6

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 354, 510, 166, 645 is 1
