Given numbers are 168, 406, 545, 220

The list of prime factors of all numbers are

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 406 are 2 x 7 x 29

Prime factors of 545 are 5 x 109

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 168, 406, 545, 220

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

Apply this formula for all numbers.

Step1:

LCM(168, 406) = 4872

GCD(168, 406) = ( 168 x 406 ) / 4872

= 168 / 406

= 168

Step2:

LCM(14, 545) = 7630

GCD(14, 545) = ( 14 x 545 ) / 7630

= 14 / 545

= 14

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 168, 406, 545, 220 is 1
