Given numbers are 437, 420, 249, 266

The list of prime factors of all numbers are

Prime factors of 437 are 19 x 23

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 249 are 3 x 83

Prime factors of 266 are 2 x 7 x 19

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

Given numbers are 437, 420, 249, 266

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

Apply this formula for all numbers.

Step1:

LCM(437, 420) = 183540

GCD(437, 420) = ( 437 x 420 ) / 183540

= 437 / 420

= 437

Step2:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

Step3:

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

= 1 / 266

= 1

So, Greatest Common Divisor of 437, 420, 249, 266 is 1
