Given numbers are 546, 645, 163, 208

The list of prime factors of all numbers are

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 163 are 163

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

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

Given numbers are 546, 645, 163, 208

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

Apply this formula for all numbers.

Step1:

LCM(546, 645) = 117390

GCD(546, 645) = ( 546 x 645 ) / 117390

= 546 / 645

= 546

Step2:

LCM(3, 163) = 489

GCD(3, 163) = ( 3 x 163 ) / 489

= 3 / 163

= 3

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 546, 645, 163, 208 is 1
