Given numbers are 515, 565, 90, 843

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 565 are 5 x 113

Prime factors of 90 are 2 x 3 x 3 x 5

Prime factors of 843 are 3 x 281

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

Given numbers are 515, 565, 90, 843

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

Apply this formula for all numbers.

Step1:

LCM(515, 565) = 58195

GCD(515, 565) = ( 515 x 565 ) / 58195

= 515 / 565

= 515

Step2:

LCM(5, 90) = 90

GCD(5, 90) = ( 5 x 90 ) / 90

= 5 / 90

= 5

Step3:

LCM(5, 843) = 4215

GCD(5, 843) = ( 5 x 843 ) / 4215

= 5 / 843

= 5

So, Greatest Common Divisor of 515, 565, 90, 843 is 1
