Given numbers are 248, 249, 690, 111

The list of prime factors of all numbers are

Prime factors of 248 are 2 x 2 x 2 x 31

Prime factors of 249 are 3 x 83

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 111 are 3 x 37

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

Given numbers are 248, 249, 690, 111

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

Apply this formula for all numbers.

Step1:

LCM(248, 249) = 61752

GCD(248, 249) = ( 248 x 249 ) / 61752

= 248 / 249

= 248

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 248, 249, 690, 111 is 1
