Given numbers are 153, 246, 721, 171

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

Prime factors of 246 are 2 x 3 x 41

Prime factors of 721 are 7 x 103

Prime factors of 171 are 3 x 3 x 19

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

Given numbers are 153, 246, 721, 171

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

Apply this formula for all numbers.

Step1:

LCM(153, 246) = 12546

GCD(153, 246) = ( 153 x 246 ) / 12546

= 153 / 246

= 153

Step2:

LCM(3, 721) = 2163

GCD(3, 721) = ( 3 x 721 ) / 2163

= 3 / 721

= 3

Step3:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

So, Greatest Common Divisor of 153, 246, 721, 171 is 1
