Given numbers are 154, 208, 100, 171

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

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

Prime factors of 100 are 2 x 2 x 5 x 5

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 154, 208, 100, 171

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

Apply this formula for all numbers.

Step1:

LCM(154, 208) = 16016

GCD(154, 208) = ( 154 x 208 ) / 16016

= 154 / 208

= 154

Step2:

LCM(2, 100) = 100

GCD(2, 100) = ( 2 x 100 ) / 100

= 2 / 100

= 2

Step3:

LCM(2, 171) = 342

GCD(2, 171) = ( 2 x 171 ) / 342

= 2 / 171

= 2

So, Greatest Common Divisor of 154, 208, 100, 171 is 1
