Given numbers are 627, 280, 155, 810

The list of prime factors of all numbers are

Prime factors of 627 are 3 x 11 x 19

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

Prime factors of 155 are 5 x 31

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 627, 280, 155, 810

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

Apply this formula for all numbers.

Step1:

LCM(627, 280) = 175560

GCD(627, 280) = ( 627 x 280 ) / 175560

= 627 / 280

= 627

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 810) = 810

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

= 1 / 810

= 1

So, Greatest Common Divisor of 627, 280, 155, 810 is 1
