Given numbers are 270, 645, 230, 991

The list of prime factors of all numbers are

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 645 are 3 x 5 x 43

Prime factors of 230 are 2 x 5 x 23

Prime factors of 991 are 991

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

Given numbers are 270, 645, 230, 991

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

Apply this formula for all numbers.

Step1:

LCM(270, 645) = 11610

GCD(270, 645) = ( 270 x 645 ) / 11610

= 270 / 645

= 270

Step2:

LCM(15, 230) = 690

GCD(15, 230) = ( 15 x 230 ) / 690

= 15 / 230

= 15

Step3:

LCM(5, 991) = 4955

GCD(5, 991) = ( 5 x 991 ) / 4955

= 5 / 991

= 5

So, Greatest Common Divisor of 270, 645, 230, 991 is 1
