Given numbers are 208, 166, 858, 551

The list of prime factors of all numbers are

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

Prime factors of 166 are 2 x 83

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 551 are 19 x 29

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

Given numbers are 208, 166, 858, 551

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

Apply this formula for all numbers.

Step1:

LCM(208, 166) = 17264

GCD(208, 166) = ( 208 x 166 ) / 17264

= 208 / 166

= 208

Step2:

LCM(2, 858) = 858

GCD(2, 858) = ( 2 x 858 ) / 858

= 2 / 858

= 2

Step3:

LCM(2, 551) = 1102

GCD(2, 551) = ( 2 x 551 ) / 1102

= 2 / 551

= 2

So, Greatest Common Divisor of 208, 166, 858, 551 is 1
