Given numbers are 660, 249, 851, 231

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 249 are 3 x 83

Prime factors of 851 are 23 x 37

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 660, 249, 851, 231

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

Apply this formula for all numbers.

Step1:

LCM(660, 249) = 54780

GCD(660, 249) = ( 660 x 249 ) / 54780

= 660 / 249

= 660

Step2:

LCM(3, 851) = 2553

GCD(3, 851) = ( 3 x 851 ) / 2553

= 3 / 851

= 3

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 660, 249, 851, 231 is 1
