Given numbers are 856, 406, 202, 551

The list of prime factors of all numbers are

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 406 are 2 x 7 x 29

Prime factors of 202 are 2 x 101

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 856, 406, 202, 551

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

Apply this formula for all numbers.

Step1:

LCM(856, 406) = 173768

GCD(856, 406) = ( 856 x 406 ) / 173768

= 856 / 406

= 856

Step2:

LCM(2, 202) = 202

GCD(2, 202) = ( 2 x 202 ) / 202

= 2 / 202

= 2

Step3:

LCM(2, 551) = 1102

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

= 2 / 551

= 2

So, Greatest Common Divisor of 856, 406, 202, 551 is 1
