Given numbers are 280, 620, 851, 810

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 851 are 23 x 37

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

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

Given numbers are 280, 620, 851, 810

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

Apply this formula for all numbers.

Step1:

LCM(280, 620) = 8680

GCD(280, 620) = ( 280 x 620 ) / 8680

= 280 / 620

= 280

Step2:

LCM(20, 851) = 17020

GCD(20, 851) = ( 20 x 851 ) / 17020

= 20 / 851

= 20

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 280, 620, 851, 810 is 1
