Given numbers are 810, 775, 560, 551

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 775 are 5 x 5 x 31

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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 810, 775, 560, 551

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

Apply this formula for all numbers.

Step1:

LCM(810, 775) = 125550

GCD(810, 775) = ( 810 x 775 ) / 125550

= 810 / 775

= 810

Step2:

LCM(5, 560) = 560

GCD(5, 560) = ( 5 x 560 ) / 560

= 5 / 560

= 5

Step3:

LCM(5, 551) = 2755

GCD(5, 551) = ( 5 x 551 ) / 2755

= 5 / 551

= 5

So, Greatest Common Divisor of 810, 775, 560, 551 is 1
